Sparv-sbx-freeling

Added

- Progress output (visible progress bar while annotating)
- `timeout` config variable to prevent Freeling from hanging indefinitely
- Fallback value for UPOS tags (in case conversion from POS fails)

Changed

- The error message reporting that some text could not be analyzed is now a Sparv warning instead.

Fixed

- Freeling process now terminates properly when aborting an annotation

Added

- Added a plugin manifest

Changed

- Adapted to the latest changes in the Sparv Pipeline (v5.0.0).
- Package has been renamed to sparv-sbx-freeling.
- Removed the unnecessary word export (this is handled by Sparv's misc module)

Fixed
- `sentence_chunk` is now an optional input.

Bug fix:
- avoid writing empty token files (e.g. when FreeLing crashes)

Improvement:
- Ignore the 'No rule to get short version of tag' error (http://nlp.lsi.upc.edu/freeling/node/655)
