Added ability to do union queries, started refactoring UpdateAdapter to expect either UserActivity or History
Apply correct user join and union with history table to task comments fragment
Added an object to encapsulate fetching history
Made addToArray method able to handle null arguments
Several changes to history model, bug fixes to FetchHistory, and placeholder display of history in UpdateAdapter to prove it works. It's pretty legit.
History uuid should be a string, for uniqueness sake
Store task titles in history models, save users the history api tells us about
Added a list of column names we expect to see in history, started building skeleton of real display logic
Implemented several more display strings
Several more history displays
Fixed some history display bugs
Fixed display of completed/deleted history items
Implemented history display repeat logic
Join with the users table to display who made each history entry
Display tag_added/removed history (will work once server sends the hash including name)
Use the same kind of union query for EditNoteActivity that we do for TaskCommentsFragment
Add a tag data column for keeping track of history fetch times
Fetch task history in EditNoteActivity
Sync history and comments in both comment fragments
Synchronize comment/history fetch callbacks
