Dave Collins a8fe1ad5fe txscript: Code consistency and doco improvements. 
This commit contains a lot of cleanup on the txscript code to make it
more consistent with the code throughout the rest of the project.  It
doesn't change any operational logic.

The following is an overview of the changes:

- Add a significant number of comments throughout in order to better
  explain what the code is doing
- Fix several comment typos
- Move a couple of constants only used by the engine to engine.go
- Move a variable only used by the engine to engine.go
- Fix a couple of format specifiers in the test prints
- Reorder functions so they're defined before/closer to use
- Make the code lint clean with the exception of the opcode definitions
