Fixes for various export related issues

[twinkarma]

• Resolves "Anonymous" export is not anonymous when using JSON format #345
  • Username now anonymized for both name field and keys inside annotation_sets
  • Configurable string prefix added to anonymized name (settings.ANONYMIZATION_PREFIX), defaults to annotator
  • Fixed the tests to check the anonymization
• Resolves Check, for documents uploaded originally in BDOC/GATE JSON format, are exported correctly as BDOC/GATE JSON format #346
  • Append to the features field if exporting as GATE format
  • Updated test_export_gate to check for this
• Resolves Remove unnecessary nesting when exporting annotation features #347
  • features field for each annotation now directly has content of the annotation instead of being nested in a label field
  • Updated check_raw_gate_annotation_formatting to check for this
• Resolves If a document is uploaded with an existing annotation_sets field. New annotations should be appended to this field rather than overwritten. #348
  • Existing annotations are merged with new annotation. For JSON exports it's the annotation_sets field while for CSV it's annotations field
  • If keys conflict, new annotation overwrites the older one
  • Updated check_raw_gate_annotation_formatting and test_export_csv to check for this behaviour
• Updated docs to reflect these changes.

@ianroberts @davidwilby can either one of you have a look at this before we merge it in?

[ianroberts]

All LGTM now - I've rebased on latest dev, combining your changes with mine from #399, and I'm happy to merge this now.

I've updated the teamware_status to use the same anonymized names as everything else.
