Logic changes to installer: 

* Protect more code with try/except blocks, hoping to crash less in some strange circumstances we haven't been able to reproduce, including the KIS 8 problem. (Updates #925. ON ERROR RESUME NEXT)
 * Instead of deleting an old Aegisub.exe, rename it to aegisub32.exe to teach Windows Distributed Link Tracking thingy that it's in fact the same thing, just with a new name.

Originally committed to SVN as r3738.
