Allow the user to pick a player name for offline mode.
Big auth refactor. Now using session objects instead of the accounts themselves.
Sessions only last for one instance start and hold all the auth and player data.
* ProgressProvider now has an abort() call
* Abort button support added to the progress dialog
* YggdrasilTask and MojangAccount adapted to support abort
YggdrasilTask will time out after 10 seconds of no network activity, or when the user pushes the Play Offline button.
In offline mode, all instance update tasks are skipped! This will need further work.
Added missing licenses
Added a Java functionality checker (detects 32/64bit java)
Refactor of *Update - no longer based on BaseUpdate, but Task directly
Fixed runner script to not derp up on 32bit linux. Could add more detection and error reporting there.
Resources are now split into graphics and generated. Generated resources are placed in the build tree and included from there.
Used the Java checker in the main settings dialog (TODO: instance settings).
Partial support for ${arch}-using libraries - both 32 and 64 variants of ${arch} are downloaded.
* Adds support for listing all objects in an S3 bucket.
* Renames a bunch of network related classes (Download->Action)
* Net actions now have static constructors
