Installs with "requires" replace previous game settings

[Letiliel]

Installing a mod/patch/wathever on top of a game will erase previous game-level configuration. It should keep existing config and only replace settings that are set in the script.

Ok, so the thing is that 'requires' was not meant to be used this way. It was originally made for one game to depend on another (example, you need Quake 2 to install Quake 2: the Reckoning). The installation process resulted in 2 distinct config files.

I'm going to try and handle this use case, but as an experiment (will still be in 0.3.5 but we may rework this whole thing for 0.3.6)

This should be fixed, and btw it's now possible to call task from different runners than the original one (for example "wine.set_regedit").

Ok, very cool !

I have opinions on how we could handle the patches and mods, so I'll willing to discuss this later on.

Yes, we need to. The current state of things where you install patches like widescreen support for flatout 2 like you install any other game feels a bit akward to me. We can do better than that.
