* Moved the x86 emitter to /common, so that plugins can link against it if they wish. * Created a new "utility" class in /common which houses string utils, fast memcpy, common exception classes, and other handy dandies. * Removed old-style linux automake files from the pcsx2 dir since they were hopelessly out of date (and their multi-file-per-line format makes svn merging impossible >_<) git-svn-id: http://pcsx2.googlecode.com/svn/branches/wxgui@1454 96395faa-99c1-11dd-bbfe-3dabce05a288
