Adds support for Fallout 2

[mrowrpurr]

Automatically detects GOG and Steam installations.

Supports profile-specific .ini files:

• ddraw.ini (sfall configuration)
• f2_res.ini (high-res configuration)

• I would love to support sfall-mods.ini too but it doesn't come out-of-the-box with GOG/Steam, it's just common for modders

Upon profile creation, fallout2.cfg is updated to use absolute paths to your game folder.

Without this fallout2.cfg change, the game results in an error when launching: "Couldn't find/load text fonts"

Save Games

• Does not yet support save game images, didn't include any specific Save Game support at all

fallout2.cfg

There is an .ini file which needs its paths updated or the game won't launch. I wasn't sure where to put this code, so I put it into initializeProfile. It works but I don't know if it's the best place to put it!
