Optimisation

[angusthompson]

Running speed must be optimised to allow for larger maps. Can be done in various ways.

• Minimise the map loops, maybe combine them all into one.
• Perhaps some sections can be done in another language.

Added pauses where necessary and optimised some functions. Freeze rate reduced from ~60% to ~20%, and zero freezing after launch.

For now, the freeze and crash rate has been reduced to zero.
