STT engine: Julius support

[Holzhaus]

IMHO support for the Julius recognition engine is desireable.

What do you think?

[charliermarsh]

Makes sense to me. I wouldn't make it a priority but seems reasonable to include. Supporting it on the Pi might end up being a bit of a nightmare so I wouldn't want to ship it with the disk image, but writing a small STT class wouldn't be a big commitment.

[Holzhaus]

Based on PR #181, I started to write basic vocabcompiler code for Julius.

[Holzhaus]

It already works (though it's a bit useless without a Julius STT engine). It's more a proof-of-concept for PR #181 ;-)

[Holzhaus]

A very basic STT Engine (including a vocabulary compiler) can be found here..
You can just save that file as client/julius.py and then run it. It'll compile a temporary vocabulary and transcribe the static/audio/time.wav file.

Refer to PR #285. Closing this.
