Upgraded babelfish to version 0.5.1
Added pyxdg version 0.25
Upgraded subliminal to version 0.8.0-dev

Use my own implementation of subliminal 0.8.0-dev with support for
matching on format (commit c142233ff93ab6b7577a77090902ab6fb2c6f6e3)
until it's implemented in subliminal master branch.
Upgraded guessit to version 0.7
Hacked version check guessit after upgrade

Set the version hardcoded instead of checking which version is installed
Added stevedore version 0.14.1
Fixed subtitle download after subliminal upgrade
Removed fake subliminal providers entry point

It's not longer needed to fake the entry points because subliminal does
not longer set them at installation (setup) time.
Updated subliminal 0.8.0-dev (h3llrais3r)

Updated to commit 905502128225035313c393189af00b83d9973693
Fixed logging after application restart
Added source (format) for subtitle matching

Use the new format from subliminal for subtitle matching and adapt
minmatchscore according to it.
Config is also upgraded.
