l10n_server 6.x-1.0-alpha4

The "preparing for Drupal 7" release.

Changes since DRUPAL-6--1-0-ALPHA3:

• #374038 report by Pasqualle: top contributors should use theme('username'), so no access denied page is linked; also implement Drupal 6 @todo item while I was at it
• #357471 by Razorraser: use l10n-community-overview class instead of ID, since it is used multiple times on the page; also fix a dl which was wrapping forms, not definition list items
• #394714 by meba, Razorrasser: Typo in groups form_alter name; also form_state is not to be taken by reference per the docs; we don't use it anyway
• #371056 by zsanmartin, meba, Razorraser: use BINARY matching for duplicate translation check, to avoid case-corrections as duplicates
• #400732 by havran: incorrect use of l() in pages.inc
• #432204 by helmo: Avoid warning when no comment is added to an msgstr entry.
• #460720 by pvasili, Dave Reid: fix parse error, ouch.
• #469288 report by ckng, fix by myself: String input was not multiline when string was short but in fact multiline
• Coding style fix: get_t() should not be used in hook_schema().
• Missed some get_t() use in hook_schema
• #524112 by myself: initial support for contexts
  - database changed to support contexts
  - update function added
  - potx requirement check updated so it looks for 6.x-3.x traits
  - storage of strings updated to 6.x-3.x potx API, and stores context now
  - filtering with contexts added (only if server has context beyond the empty one == has D7 or modules)
  (otherwise it should not distrurb existing users)
  - some display of context was added
• #524112 follow up by myself: refactor context information printing to theme function and use it in view and translation mode too
• #524112 follow ups by myself: added import and export support for Drupal 7 contexts
