Improvements to the interface, autopep8
This is a major update: I have incremented the version number to 0.9.

1. All shell operations now have their return codes checked and non-zero
   return-codes result in panic. This feature was requested by many
   users.
2. Major updates to textgrid.py (see relevant github repository)
3. Went to `str.format`-style printing
4. Status messages are improved and now printed to stderr
5. The MLF printing status message lists the number of files found.
6. Fixed possible dictionary bug.
Mostly licensing stuff...
Implemented the suggestion in Issue #10: check for digit-initial phones
and fail if they are found: HTK parses these as probabilities.
Version 1.0: speaks and understands UTF-8 label files.
Had some weird interactions with version of the "wave" module: should be
smooth now.
Added FAQ to README
Writing on readme
The hashbang in align.py was causing problems; now fixed.
Reverted to Python 2.6-style string formatting for compatibility
Brought the README up to date: Python 2.5 is not officially supported.
Version check: assuming there are no lexer/parser errors, the script
will generate an error message if run by a Python version other than
Python 2.6-2.7.
CMU dictionary's location changed...
Autopep8 and saving models instructions
idk
