SFGMidi: Fix bug in SFG MIDI interrupt slot restoration.

Makefile: Create gen and bin directories if they do not exist.

README: Change kB suffix to K.

System: Do not return values in the past from GetHighResTimerValue.

If an interrupt would occur between reading the timer LSB and MSB, it could
result in incorrect results. E.g. when the timer is 1FFH before the interrupt
and it is 280H after, the value returned would be 180H and time would run
backwards.

With this fix, if the MSB between two reads differs, it always returns 0 as the
LSB which must have been true somewhere between the MSB reads.

Heap: Move messages to the end of the file.

Class: Load ix directly in stead of with push/pop.

Synthesix: Rename to Application.

Easier copy/pasting between projects.

Heap: Rename heaps to main / upper.

Heap: Move heap instantiation to ROM.
