Multiple non-conflicting mods

[Marshall]

I haven't yet worked out all the details for the install-maker (whatever it gets called) yet.
I think that the Update Only installer will be generated by comparing two Launch Base folders - the old version of the mod and the new version. New or updated files will be included*, and a new liblist.gam created.
*I might be able to include file patching for updated files, but that will mean you can only update, for example, version 4 to version 5. You wouldn't be able to update version 3 to version 5.
Basically, the Update Only installer is only good for infrequent releases.
