v0.5-beta

Fifth release of our application. This release includes a completely revamped navigation drawer, along with a complete replacement of the action bar with the new toolbar in our three activities. Five minute warnings are now

• Group expiry warning (~5 minutes before end time) and the option to extend by 30 minutes

Planned features:
