Added STC/LOOPNE
Added tests for STC/CLC/LOOP/LOOPE/LOOPNE
Fix bug in REP/REPE/REPNE - updated tests accordingly
Changed HLT to set Registers.Halt - modified RealModeMemoryCore to initialize everything with halts, so if something screws up, the system is halted
Added support for file handles in Int21h - can open pre-existing files now
Configured environment variable segment in EXEs
Fixed starting stack segment/pointer in EXEs
Shifted top memory address of EXEs to A000:0000 (video memory). It turns out extra space is needed for data segments and libc refused to initialize without adequate space after the end of the EXE memory
New int21 - 0x3D, 0x3E, 0x43,
