Fixed|libdeng2: Missing return value in AutoRef
libdeng2|libgui|Client|Server: Defining application metadata

de::App now defines a method for setting all the application metadata in
one call without having to access Qt methods. Also, the Unix-style home
folder name can be defined from the application and is no longer
hardcoded to ".doomsday".
Merge branch 'ui-multiplayer' of https://github.com/skyjake/Doomsday-Engine into oculus-refactor
Merge branch 'master' of https://github.com/skyjake/Doomsday-Engine into oculus-refactor
Refactor|Client|libappfw: Calculate projection matrix in VRConfig

The function for calculating a projection matrix suitable for the
current VR configuration was moved to libappfw. It was also broken
down to calculate vertical FOV and view aspect as separate methods.

Merge remote-tracking branch 'origin/master' into oculus-refactor
Fixed|Unix: Crash when launching application (UnixInfo)

UnixInfo needed to know the application's /etc path, but the application
had not been fully constructed at the time.
UI|Client: Added "24-bit" color depth to Video Settings
Client|Stereo 3D: Cleanup
libappfw|Oculus Rift: Modelview matrix according to head tracking

Added a utility for putting together a modelview matrix for the tracked
head position/orientation, however this is not used by the Doomsday
client at the moment.
UI|Client: Cleanup in 3D & VR Settings

Moved the Oculus Rift specific multisampling setting below the Oculus
Rift subtitle.
Cleanup
qmake|SDK: Added sdk.pro, install rules for headers

Public headers are now specified using a macro that automatically adds
an install rule for them when doing an SDK build.
Fixed|qmake: Typo
SDK|qmake: Install libraries to the SDK directory
Merge remote-tracking branch 'origin/master' into sdk-split
libgui|Cleanup: Removed ARB_debug_output

This extension wasn't in use and seems to be subtly differently defined
on different platforms.
Cleanup|qmake|64-bit: Preprocessor symbol for 64-bit builds

Conforming to naming conventions.
qmake|libgui|Scripting: Moved gui.de to libgui

gui.de directly relates to functionality in libgui, so it should be
located in libgui's modules.

Project files updates accordingly. client.pro still handles the
installation of all Doomsday Script modules for the Doomsday client.
