Add a hyphen to 'utf8', just for consistency with how we spell it in tracebacks.py.
Merge fix for Unicode decoding error when the default encoding isn't UTF-8. FIx #58.

Switch license to MIT; include copy as LICENSE
Tersen licensing stuff a tad.

Date copyright back to when the library began.
Update readme for release, and bump version to 1.5.1.
include LICENSE in tarballs
