list: move the spinner into its own blaze component

Browse source 
This way, when a list is at the maximum number of cards shown and adding
a new card would make the spinner appear, the list would load the next
N items.

This can happen if user A and B are both looking at the same board,
B adds a new cards, and A will see the spinner and will not be able to
remove it.
