FeedAdapter now has two lists: one of visible projects, another of total projects. All methods (e.g., add, insert) work with both lists. The ordering of the list of total projects is inviolable, since projects in that list cannot be deleted or swapped.
FeedActivity uses onActivityResult to check Intent extras for project name and project color, both expected to be strings, the latter expected to work with Integer#parseInt(String, 16)... Expected to change the latter's format to String once we get a Spinner with color entries...
Deleted setOnItemLongClickListener method in FeedActivity so swapping should now work...
