This release includes the following new features:

- on-the-fly TTS tags can now be constructed with the aid of the UI
- new languages and regional variants available from Google now exposed
- can now set additional options (e.g. speed), if service supports them

- Ctrl+T (or Cmd+T on Mac OS X) usable program-wide to access add-on
- Festival service support (Linux only)

The following issues have been fixed:

- front card content excluded from playback when in answer playback mode
- generated media filenames are now unique and portable between systems
- last-used service, voice, and options are remembered between sessions
- Ekho can be used in an on-the-fly TTS tag without specifying Mandarin
  and on-the-fly TTS tag parsing is much more forgiving now on the whole
- most processing now handled by a worker thread to prevent UI freezes
- many other small bug fixes
Fix for PATH_ADDON encoding

This checks the system encoding and decodes the current working
directory into a unicode string based on that, fixing start-up crashes
when the add-on tries to read the configuration file.
Use system temporary directory

This has been put in as a fix for Windows users who cannot send
non-ASCII paths via CLI interfaces, which affects things like
transcoding. By using the system temporary directory, we can later, in
Python, move the file to its correct place.
Add note regarding sqlite

Adds a note regarding the need for the getfilesystemencoding call.
Bump version number

With this quick fix applied to the stable branch, this causes a minor
point release.
Merge branch 'qfx/nonascii-home' into develop

Brings in the quick fix that was made to the stable release for the
purposes of fixing non-ASCII home directories.
