Self-Training Convenience

Originally just some things to make it easier for me to get lots of data, but I've tried polishing it.

I deviated from the original code style, but it makes it easier for me to look at (:

Changes:

Self training:

• Session time adjustable as a constant in code
• Buffer time (Time between hitting enter and it recording) adjustable as a constant in code
• New argument overwrite which allows control over saving multiple training sessions
  • 0 is no overwrite, 1 is yes overwrite. Default is 1 (same behavior as before)

Model training:

• Can combine all .pkl files in the model\intent directory.
  • Can combine files with varying amounts of actions (A warning is given when this is done)

Obligatory :3
