Shell|GUI: Inform user about an invalid port number
Merge branch 'master' of ssh://github.com/skyjake/Doomsday-Engine
Server: Shut down if no game selected

Since shell connections are not yet available in ringzero, the server
would get stuck in a gameless, unreachable state if game selection
fails for any reason.
Shell|GUI: Passing the -iwad option to local server based on Preferences
Unix: Fixed build (missing header)
Optimize|Server|FS1: Composing server info

The CRC of the loaded files (i.e., IWAD) was recalculated every time
a serverinfo_t was composed. This is done every tick for the Beacon
so it needs to be efficient. Now the loaded files CRC is cached in FS1.
Windows|Installer: Added server, shell, deng_shell, deng_gui to the deployment
Shell|GUI|Ubuntu: Default font for the console widget
libshell|Unix: Finding the doomsday-server binary for LocalServer
Documentation|libshell: Fixed a few Doxygen warnings
All Games: Fixing warnings about pointer types

As thinkers are used in a polymorphic manner, the appropriate pointer
type in the argument is void *.
All Games: Fixed more thinker function type warnings
Snowberry: Dropped starting of a server

Servers are now started using the Shell, not through Snowberry. Removed
the options and code for launching a dedicated server in a terminal.
Updater: Cleanup
Shell|GUI|Unix: .desktop shortcut file for the Shell

Added the .desktop file and an application icon for the Shell.
Shell|GUI|Unix: Added .desktop file for the Shell
Windows|Installer: Added shortcut icons for the Shell

Both in the program group and on the desktop.
Installer|Mac OS X: Revised distribution to use PackageMaker

As the Shell needs to be installed, too, the Mac distribution packages
now use an .mpkg that installs both the engine and the Shell application.

Builder|Mac OS X: Renamed distribution package wrt 32/64-bit

The 64-bit package is now the default, so the 32-bit one is identified
as "_32bit.dmg" while the first one is just ".dmg".
