Mac OS X launcher

The Mac OS X version of Chocolate Doom includes a minimalist launcher program for selecting the IWAD files to use and starting the game. The purpose of this is to make installation of Chocolate Doom on OS X straightforward and congruent with the rest of the operating system.

A brief list of features:
 * The source port is packaged as a .DMG archive, and Chocolate Doom can be installed simply by dragging the "Chocolate Doom" icon into the Applications folder.
 * The locations of the IWAD files for various games can be configured.
 * Extra command line parameters can be entered.
 * Launching of PWADs and dehacked patches is straightforward, as the launcher includes file associations for .WAD and .DEH files. Double clicking on a PWAD in the Finder configures the appropriate command line parameters to load the game with the PWAD.
 * The setup tool can be accessed from a button in the launcher window.
 * "Command Prompt" menu option allows a terminal window to be opened which is preconfigured with environment variables to allow the game to be started.
