Add '-findiwads' command line hack so that the setup program can find out what games are installed. Provide a drop-down list in setup to allow the game type to be selected. Subversion-branch: /trunk/chocolate-doom Subversion-revision: 803

-* Smarter setup program - detect IWADs automatically and make them

* Free version of the Chocolate Doom logo (from scratch, not using the
Doom imp sprite), so t-shirts can be printed!
* Better icon for chocolate-setup.
