[new] games/dsda-doom

Hi,

This is a port for DSDA-Doom.

DSDA-Doom is a new DOOM source port based on prboom-plus. It has extra
tooling for demo recording and playback, with a focus on speedrunning.
It also implements several new standards for mod and map authors alike.

Noteworthy features include the hability to rewind the game; support for
Heretic and Hexen (two games based on DOOM, but with a wizardry/medieval
theme); and support for UMAPINFO, in which a WAD can provide meta-data
associated to levels, such as the level author, the name of the music
playing in the level, etc.

DSDA-Doom has gained popularity among DOOM players and the users of the
doomworld.com forums.
