UI|Client: Tweaked information in the About dialog
Fixed|ClientApp: Potential uncaught exception when alerting without a window
libdeng2|Range: Added utilities for finding and printing contiguous integer ranges
Renderer|Particles: Don’t warn needlessly about missing particle textures

Instead of warning, print an INFO-level message about which textures
were successfully loaded.

Warnings are still printed if loading of an image file fails.
UI|Client: Tweaked clip-culling for scrolling

When scrolling, it is beneficial to have things ready before they
become visible. Clip-culling will now use a hardcoded safety boundary
around the widget’s actual rectangle.
Typo
Fixed|Bindings|Multiplayer: Crash when more than one client in the game

When checking for player controls, a null pointer was accessed
in P_IsControlBound().
Fixed|libcommon: Don’t check control input of remote players

Remote players are moved according to a smoothed path of received
coordinates, not any control input values.
libcommon|UI: Make sure game is frozen before opening a network connection
Fixed|Shell|libshell: ServerFinder must work without a de::App
Fixed|Shell|OS X: Use the correct UI font (Lucida Grande)

IssueID #1703
Refactor|Client|Server|libgui: Checking for existence of singletons

Renamed methods that check for singleton existence to
“somethingExists()”. Also don’t have redundant methods in ClientApp
and ServerApp for this purpose.
Stereo 3D|UI: Clarified terms used in the VR settings dialog
Fixed|Sky|Renderer: Sky rendering issues/HOM in Hexen (refactoring oversight)
Resources|Windows|Mac OS: Automatically search for IWADs installed via Steam

Doomsday will now search the platform specific SteamApps directory
on Windows and OS X when locating IWADS, unless the the -nosteamapps
command line option is specified.
Windows: Use backslashes when querying the registry via QSettings

Evidently one must use backslashes else the query will fail.
Refactor|Game: Game now uses de::String and de::Path to represent attributes
