Update System.prop

Added edit "ro.config.hw_fast_dormancy=1" for testing. Worked well with CM7 and the Stock/Harmonia Roms for the Evo saving a noticeable amount of juice so testing its effectiveness with CM10.

Also added line for "libqc-opt.so" needs more testing but the line has been found in every other Rom I have seen that includes "libqc-opt.so".
