Dave Collins cbda064842 Import btcscript repo into txscript directory. 
This commit contains the entire btcscript repository along with several
changes needed to move all of the files into the txscript directory in
order to prepare it for merging.  This does NOT update btcd or any of the
other packages to use the new location as that will be done separately.

- All import paths in the old btcscript test files have been changed to the
  new location
- All references to btcscript as the package name have been chagned to
  txscript

This is ongoing work toward #214.
