write pocketsphinx decoder output to debug logger
Rewritten vocabcompiler and separated it from pocketsphinx logic

The pocketsphinx part of vocabcompiler now uses the cmuclmtk wrapper libary for compilation of the languagemodel/dictionary.
A revision check has been implemented, so that vocabulary won't get recompiled if there's no need.
Proper integration into jasper.py, client/stt.py and client/test.py is
still missing due to pending pull requests that change these modules.
Added DummyVocabulary class
Changed vocabcompiler test cases
Add error handler for cmuclmtk import to vocabcompiler
