Bangs/Plugins: Remember when a setup module has been installed

[GnaspGames]

When using a bang command, such as !loop and !event you have to install a 'setup module' for features to work.

Currently you are prompted to do this once everytime you compile a file using these commands.

I want to add a "cache" to the .smelt folder, which will contain the compiled setup modules, and will only prompt you to install if the file (a) isn't there, or (b) has changed.

When you are prompted to install a setup module, it should be clear that this needs to be done now, and that it won't be repeated later.
