Can now add debt items

Users now have the ability to add debts to/from any of the other
roommates in the house
Starting to add functionality of paid debts

The add/edit screen now has the ability to set the debt as paid, and the
other screens reflect this information appropriately.
Default value of MultiSelectionSpinner is now accurate

The MultiSelectionSpinner defaulted to a value of the first roommate's
name even if he wasn't selected. Now it displays "(nobody)" when no
roommates are selected
DebtAmount now has debtId in it
Editing existing debts now partially pre-fills, needs completion
changed the title for announcements to say roommate 1 instead of long string
Announcements now posts updates from other fragments

Adds "Announcement: " if the post is added from announcement fragment,
"Notification: " otherwise. Changing colors for items in the listview
seems rather complicated and I would have to make a custom adapter but I
can look into it if I have more time this week.
You can now edit existing debts by clicking on them
