superwow: move into its own module

Moving superwow integration from thirdparty into a seperate module.
It's a client mod, not an addon and therefore should not bloat the
thirdparty section that is already huge enough.

It was a mistake to treat it as an addon-compat in first place.

Now having it as a seperate module also allows it to grow better
over time as new SuperWoW features are integrated into pfUI.
