Big update; should fix most or all of the problems introduced in recent revisions. Extended summary follows: 

New EE/IOP sync method: The EE can now "throttle" itself between high and low resolution wait cycles.  High res cycles are engaged when certain time-critical ints and BIOS calls are done.  Meanwhile, low-res mode uses much less cpu.

vs2008 project: Added a "PUBLIC" define to the 'Release (to Public)' build type.  It can be used to ifdef code that should only be excluded when creating official builds and releases.

Renamed INT() macro into CPU_INT() function.  INT() is also a Win32 define so renaming helps alleviate confusion and lets VS IDE's code database browser work better when trying to list references of the function.

Fixed some lingering inaccuracies in the EE h/vsync counters introduced at r246.

Removed the Use Fast Branches option (for now) as it's not compatible with the new EE/IOP sync (yet).

Added fflush() to the emu log so that it doesn't get cut off prematurely if the emulator crashes.
