Mod installation folder

[ZhilkinSerg]

Cataclysm mods can be loaded from at least two folders:

• \data\mods;
• \mods.

I suggest adding an option to define mod install location.

I guess this was added somewhat recently CleverRaven/Cataclysm-DDA@6a31c5a . I'll try to include this in the next release.

Isn't the second directory %LOCALAPPDAT%\cataclysm-dda\mods instead of the one from inside the game directory on Windows? I'll have to confirm this to progress on this.

I guess it's the one inside the game directory. This is so confusing to me.

So both \data\mods and \mods need to be checked for mods and an option need to be added to select where you want to install them.

These paths are relative to game directory.
