All fancy UI removed for performance
Streamlined login, logout
Reading device contacts implementation WIP
Friend logic added (WIP)

Next, I’ll branch out of this code to investigate whether having a
single groups store that loads remotely is better than maintaining 3
local group stores.
Groups store is now unified and remotely loaded

UX so no ‘submit’ button exists on group create page + Group CRUD with
friends selection now working
Fixed reading contacts from iOS

Re-installed Phonegap due to issues with reading phone contacts. Also,
changed the styles on message boxes so no shadows are used anywhere in
the app.
Quicker animations, Next: Make friend store remote
Fixed cloud function for setting friends

includeKey is still an issue!
Fixed animations, sorters, and other misc
Fixed most of hide() and show() mess + animations

Tweaked UX for creating groups – seems more intuitive now
Unformatted iOS device contacts dummy data
Merge branch 'onegroupstore'
