Implemented a feature that give a project and optional default context. When set,

this context will be pre-populated when creating an action from the project's page.
When creating an action from the home page, the context will be auto-selected when
the project is selected if the context field has not yet been entered.

This implementation is a combination of the great patch submitted by James Kebinger
(thanks James!) and some of my modifications and additions.

Don't forget to rake db:migrate.

Fixes #162, originally suggested by Rolf one year ago!

Also in this commit:

 * Tweaked selenium tags test
 * Tweaked formatting of next/previous project HTML
 * Implemented Null Object pattern for context to support
   a Project having no default context
 * Removed tickler.rhtml, no longer in use
 * applying z-index values to project sortable list items (otherwise context
   autocomplete was appearing below next list item)
 * Swapped order of project and context in new action form (setting default context
   makes more sense this way)
 * Removed CSS width of for form elements, so form could be used in content area
   without being too narrow
