Added:

* TICKSPEED builtin counter that returns the current tick speed, from 0 (fastest) to 4 (normal) to 8 (slowest).

* Faster tick speeds will cycle bottom text every 2 ticks instead of every tick, matching normal speed cycling.

* Loading the same file, or running the same function, multiple times in a row (or recursively) will not cause a file read each time; instead it will be stored in and load from conventional memory.
