tags for compilations

We have some compilations in UVL for various reasons, mostly because there is something interesting beyond being just a collection of games. I think we ought to tag these reasons. This is not just for searching, it also shows users, new editors, and potential editors, why a certain compilation is included while most are not.
compilation-port includes game(s) ported from other platforms (Super Mario All-Stars, Sega Classics)
compilation-emulation includes emulated game(s)
compilation-exclusive compilation includes exclusive-to-this-platform game(s)
compilation-exclusivereleased compilation includes game(s) that was originally released as a platform exclusive
compilation-prototype includes prototype/beta game(s)
compilation-unreleased includes previously unreleased game(s)
compilation-rare includes rare game(s)
compilation-regiondenied includes formally region-denied game(s) (Not previously in Europe, Japan exclusive, etc.)
compilation-fixed includes game(s) with a fix or workaround for issues dealt with poorly (or not at all) in the original.
compilation-alternate includes alternate content for game(s)
compilation-newcontent includes new content for game(s)
compilation-censored (patet)
compilation-uncensored (patet)

There's some overlap with port variants with those if the compilation is for different platform (usually the case).


Exclusive to the original platform or to current one?

Current. But thank you for noting the situation of when "platform exclusive" games end up in a compilation.
