Bugfixes and upgrades:
1. AllowDVDV: the clean target was added, and Rules.make was replaced with one that actually works.
2. Projects within the oldlibs are now pre-compiled and stored within oldlibs/bin/, since they won't be updated too much.
3. Updated uLaunchELF to work with the new libcdvd library.
4. Brought the month bugfix over to vmc_fs: the month field needs to have the most significant bit filed off, since the old CDVDMAN module doesn't do that automatically.
5. Removed the PS2SDK preparation scripts. I plan to make uLaunchELF rely on only fileXio, so they will get deleted sooner or later.
6. Removed the chkesr RPC module. ESR discs will now be checked from the EE, with the standard libcdvd.
7. The libcdvd initialization mode within the libcdvdfs IOP module has been changed to 1, so that uLaunchELF can start up on all consoles, even with disc control enabled when there isn't a disc inserted.
