Aligner ignores custom dictionary entries when running HTK

[chrisbrickhouse]

The HVite command is constructed at line 465 and part of the command specifies the dictionary file to be passed to HTK (line 477). Currently, the only dictionary passed to HTK is the CMU dictionary distributed with FAVE. If an alignment is attempted with a custom dictionary, HVite will fail saying that a word is not in the dictionary even if a transcription is given in the custom dictionary. This can be confusing for users to debug and fix.

FAVE should merge the default dictionary and any included dictionary, and then pass both as part of the HVite command so that custom dictionary inclusion works as intended.
