reloadbasic: ~2.7x faster translation!

Nearly five seconds to translate common.rbas has *really* been getting on my nerves

Total compile times for a clean rebuild have reduced to about 2/3rds

Interestingly pretty much 100% of time is spent in pyPEG.py; generating
the .bas file takes negligible time.
To speed it up I added several early exits to some parsing rules.
I already spent a lot of effort optimising pyPEG years ago, so
I'm not too hopeful about speeding that up further... however,
pyPEG 2 was released.

It would still be very nice to break up the gargantuan common.rbas,
customsubs.rbas and loading.rbas to reduce recompile time.
