Main method extracted to separate file to make it easier to test the _rest_ of the code.
munit is added as a submodule by running `cd src; git submodule add https://github.com/nemequ/munit.git` .
Unit testing has so far only been tested on ubuntu.
Used code formatter to correct indentations and align all {} in lACMD(do_exits)
Checked for unmactched braces and found none.
My code editor shows all {} are matched.

Fixes unguarded blocks of code in ACMD(do_exits) that could cause the server to report scripted trigger events (mob movements, exit links to rooms being reassigned, and doors being opened or closed) as script errors. Particularly, if this code is copy and pasted into the do_auto_exits().
Fixes the display order of objects in obj_to_room().
Objects are now displayed in the order they are placed/dropped. This prevents fountains, boards, etcetera from "moving" around the room.
This corrects an issue encountered when loading world information on the Raspberry Pi. Sometimes, there is a ~ stored in the memory location in front of tmp char array. The for loop will decrement below the starting memory address, making it read the ~ and think it's at the end of the room, causing an error and preventing the MUD from loading.
This change checks the memory address of tmp, ensuring it is > the starting memory address before decrementing it in the for() loop. Then, the if/else checks to ensure the carriage return and newline are properly placed to prevent duplication.
* Make sure all followers are free'd before freeing the character list
Otherwise, the followers structs will point to free'd memory and
the stop_follower call will attempt to dereference a free'd
characters' followers list.

We're leveraging the lookup table, because it's a safer way
to see if an object has been free'd than looking at the object
itself (which while it may work may just as well fail).

* https://github.com/tbamud/tbamud/issues/79 typo

* NUM_AFF_FLAGS fix.
Now, consistently, the NUM_AFF_FLAGS is used in the same way as other
NUM_* variables. Specifically, the the number is consistent with
how others are defined - 1 above the highest in the list.
I would like to have removed the need to start from 1 instead of 0
as well, but the loading mechanism, and thus potentially a lot of
existing object files, use 0 as a marker for "no flags set", and
we can't easily fix that. So, the places we loop through the list,
we still need to make sure we're stying within the [1;NUM_AFF_FLAGS) interval.
Simultaneously, I've checked over the other flags, and it seems like
the usage is pretty consistent there.

* make Makefile more portable
tbamud doesn't build on FreeBSD or OpenBSD. This series of commits are meant to make those builds work by making the Makefile more portable.
I should mention that I've never used tbamud before today, so please read my pull request carefully.
This commit itself fixes the first issue encountered. I assume wildcard and patsubst are gmake-only.
* Update Makefile.in
It turns out using the backslash to escape newlines in this situation is not portable.
* Delete Makefile.in
Will re-add. There are problems with this file. It's marked executable when it shouldn't be, and has ^M characters which prevent builds on OpenBSD.
* re-add Makefile.in
* Add build generated files to .gitignore
* Fix error in "last all" output and resolve Wunused-result warnings
- Check return value of several standard library calls that could
return error states.
- Fix issue with "last all" command (it sent tabs for alignment
that were reinterpreted as colors).
* Fix buffer overflow in do_export_zone command
* Replace a few strcat/sprintf instances with bounded variants
Also cleaned up the whitespace in the parse_edit_action function as it was
not consistent.
Fix bug in editor format command introduced in earlier commit
* Fix bug in editor toggle command when an escaped @ is in the buffer
Previously, toggling between @ and \t would always try to convert
@ to \t, even if already toggled, iff an escaped @ was present in the
buffer (i.e. '@@').
Replace a few sprintf calls with snprintf to prevent buffer overflow.
Added error messages to the logs where buffer size prevents a room,
object, mobile, or quest from being saved to disk.
* Fix several misleading indentation warnings on GCC 8.1.1
* Fix reliance on undefined strcpy/sprintf behavior (-Wrestrict warnings)
The standard states that strcpy results in undefined behavior when the source
and destination buffers overlap. I resolved this with a combination of memmove
and strlen. Note that the resulting code is slightly less efficient.
Similarly, sprintf's behavior is undefined when copying takes place between
objects that overlap. I replaced most of these with a simple strcat, though
one required a temp buffer.
* Fix format in improved-edit.c to match surrounding code
