WadMapConverter: Cleanup
WadMapConverter|Id1Map: Applied pimpl idiom to Id1Map; cleanup
Refactor|WadMapConverter|Id1Map: Cleaned up the Id1Map API
Refactor|WadMapConverter: Removed the unnecessary MapLumpInfo; Id1Map cleanup
Refactor|WadMapConverter: Further Id1Map cleanup
WadMapConverter: Cleanup
WadMapConverter: Removed the now unused maplumpinfo.h
WadMapConverter: Bumped version number to 1.1.1
Fixed: Compiler warning (explicit de::IPrivate init in copy-ctor)
libcommon: Initiate map briefings from the main thread
World: Switch to busy mode on engine side, when changing the current map

Initiating busy mode on engine side allows splitting this task into
multiple subtasks. Also, in the future it may not be necessary to
switch to busy mode at all, provided the new map is already loaded.
World|Map: Added cmd "inspectmap" for logging details of the current map

The 'inspectmap' command can be used whenever the user is interested
in knowing detailed information about the current map. Presently this
information is limited to the total number of each type of map data
element in the map, however.
Fixed|WadMapConverter: Build failure (missing Doomsday API header)
libgui|GLFramebuffer: Fall back to no depth/stencil texture (just color)

It is conceivable that some OpenGL drivers do not support a
depth24/stencil8 texture in a FBO attachments. In this case, we’ll
try to make do without depth information.
libgui|GLInfo: Check for FBO-related OpenGL extensions

If missing, warnings are printed in the log.
Renderer|Oculus Rift: Apply multisampling in unwarped frame buffer

This multisampling is intended to counter the 1.5x scaling. The
warping is smoothed out by using a linear filter on the color
texture. The end result: less jaggies.

Todo: Make configurable via a settings dialog.
Refactor|libgui|GLInfo: Better name for a method
Fixed|UI|Automap: Clipping of the automap when sidebar is open

The normalized coordinates should be agnostic of the game widget’s
size and position, so normalize against the widget instead of
the full view.
Cleanup
UI|Client|Oculus Rift: Draw a custom mouse cursor in Oculus Rift mode

The cursor is simply a LabelWidget that shows the old mouse cursor
image. It is moved to the coordinates of the real mouse cursor.
