Navigation Drawer

Add a left side navigation drawer to the changes list, change details, change diff and projects screens allowing for quickly going back to the changes list, viewing starred changes and changing among recently used Gerrits. It also shows more clearly whether the user is logged in to the current Gerrit and their details.

Notable changes:

• Migrate from support-v4 to support-v7 and the AppCompat library
• Move fragment inflation out of layout to fix crashes when using the AppCompat library
• Enable MultiDex as we now have over 65K methods (thanks to some very large libraries)

@JBirdVegas I cannot get this to build due to failing dependencies on travis. Can you update the Android SDK on Travis and Jenkins (mgerrit.org) then I will be able to release this.
