atj: provide default output prefix/filenames on unpacking

If no output prefix is specified, a default is picked:
- filename with extension replaced by .afi for FWU files
- filename with extension replaced by .fw/ for AFI files
- filename without extension and with / for FW files

Allow USB IDs to be non-unique.

When retrieving USB IDs create a list of players matching to a USB ID instead
of assuming only one player.  This prevents non-unique IDs overwriting each
other and will be used for improved autodetection later.

Currently only the first ID is used during detection, and no additional IDs
have been added yet.

Don't assume success for TTS object creation.

While the current implementation of getTTS() will always return an object this

Factor out executable based TTS engines to separate subclasses.

Similar as done with SAPI / MSSP make the current implementation for executable
based TTS engines a base class and create derived classes for each supported
TTS. Removes the need for the implementation to know about the individual TTS
engines.

Add support for speaking directly (i.e. without going through a temporary wave
file, currently only used by espeak).
