Enhancement patch: Up to 20% compile speed improvements

[GoogleCodeExporter]

In my application (with a deeply nested hierarchy of templates), this patch 
provides a 20% and up improvement to compile times by caching pattern lists, 
and speeding up restriction checks.  Testing speed against the included tests 
provides a more modest 5% speedup.

Thanks. I made a few changes and brought that from ~20% to ~28% faster.

Testing performance using crunner.py isn't really accurate so I used this line 
with a large, representative template (73K, 1600 lines, 5700 words, 20k tokens).
