Preset-oriented graphical launcher of ZDoom and derivatives

Doom Runner is yet another launcher of common Doom source ports (like GZDoom, Zandronum, PrBoom, ...) with graphical user interface.
It is written in C++ and Qt, and it is designed around the idea of presets for various multi-file modifications (Brutal Doom with mutators, Project Brutality with UDV, Complex Doom Clusterfuck, ...) to allow one-click switching between them and minimize any repetitive work.
