microVU: more flag "stuff" xD 

<JakeStine>cotton: your commits always contain "stuff"
<JakeStine>I think you should rename one of your files to "microVU_stuff"
<Dwarg>And maybe others called "microVU_junk" and "microVU_crap"
<Dwarg>Then you could be much clearer
<Dwarg>"Fixed some junk, broke some crap, added some stuff...."
<JakeStine>lol
<cotton>lol
