* Split off q_platform.h from q_shared.h
* Removed lcc PATH hack and replaced with something slightly less hacky * Removed all platform specific hostfiles from lcc and replaced with bytecode.c (from ankon) * Turned lcc option "-S" on permanently * Improved q3cpp so that it recursively adds include dirs to its list
