WineWrap failing silently

[drostev]

When trying to install The Witcher 3 through WineWrap, I was left with an empty installation directory. Running GameHub from the terminal let me see that WineWrap was failing due to a missing package (icoutils.)

The closest thing to an error message was a notification that GameHub could not find the game's executable after WineWrap had "finished." Is there some way to detect that WineWrap has exited abnormally and abort the installation?

IMHO, either WineWrap should allow the scripts to work without icoutils or GameHub should warn the user before using WineWrap without icoutils installed (as it works with innoextract)

I also mentioned in #156 that WineWrap's dependencies should be listed as optional deps for the GameHub packages. Warning the user before installation sounds like a good idea.
