Mostly playing with branches on an actual issue

Learning about git branches on an actual problem
Reset inverted conditional opcodes

changed back to logical conditions. Maybe the problem is with how/when the flags are set(tetris executes first ~16000 opcodes perfectly).
Removed useless macros in opcodes header

removed useless macros for conditional opcodes in opcodes.h file
Merged test branch with master

I should probably debug opcodes that modify flags instead of conditional branches
