txscript: Optimze typeOfScript pay-to-pubkey

Browse source 
This continues the process of converting the typeOfScript function to
use a combination of raw script analysis and the new tokenizer instead
of the face less efficient parsed opcodes, with the intent of
significantly optimizing the function.

In particular, it converts the detection of pay-to-pubkey scripts to use
raw script analysis.
