Started implementing sqlFrontend for admin interface

- It will allow export/import of database dumps
- It shall aid fetching database updates
- Currently only export is working
Topmost todo item is my current quest.

I've got to look through the sound files whenever sound files are added/changed or langages/words are changed.
The thing is, that there are cases where we've got sound files and no transcriptions, but only words and languages.
To solve this I'll add another table that maps from languages x words to sound files.
Based on this table I'll be able to:
1: Look up sound files much faster
2: Calculate dummy transcriptions
Updated sound submodule
