Windows UI: Fix some UI bugs and move more magic numbers to an enumerator.
Missed an enter/return.
Forgot to fix an if.
..And some others.
Change some enumerator names.
Adjust some of the if positioning. OCD thing, heh.
Correct Henrik's name in ppsspp.rc. For some reason, his surname's "å" was swapped with a question mark. Probably an encoding issue?
Fix typo in Henrik's name in about dialog box.
Change a couple last-minute things.
