Merge branch 'develop' of github.com:MultiMC/MultiMC5 into develop
Added vim *.swp files to .gitignore
Added data structures for Mojang Account.
Added YouCompleteMe config to .gitignore
Add abstract base class for Yggdrasil tasks.
Add test authentication task.

It doesn't actually do anything with the server's reply yet.
Implement auth task's response processing.

The authenticate task can now successfully log a user in.
Implement account list and account list dialog
Implement loading accounts from list.
Implement saving account list to file

Currently it only saves when accounts are added or removed. We'll have
to fix this, but we need signals for when account objects change first.
Add a button to open the account list.

Also fix the account list dialog's close button.
Nuke and pave the old login system

Also, account list now saves profile lists.
Implement user info stub for newest minecraft snapshot
Fix crashing when there are no accounts added

The warning message actually displays now when there are no Mojang
accounts to log in with, rather than simply crashing MultiMC.
Tweak the "no accounts" warning a bit.

It now asks users if they want to open the manage accounts dialog to
add their accounts.
Implement removing accounts.
Properly implement launching and downloading

Also added a system to select an active account to log in with.
Fix console window (now not a QDialog)

It now opens and coloses as expected, depending on user
preferences and the status of the various processes involved.
Console window geometry and state are remembered between runs.
Prepare for rework of instance launch/update

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.
