2.13 1.4-M3 to 1.4-final upgrade

2.13.1 Changes

2.13.1.1 Bug fixes

• Misc improvements to the backup tool.
• Fix too strong validation on collection names when subscrbing on collections in the user settings. (DSY-228)
• Updated Polish, German and Russian translations (Dutch were already up to date, French is missing in this release).
• PosgreSQL jar is included in the Daisy distribution.
• The backuptool zips database dumps. (this makes earlier backups incompatible)
• Fixed a StackOverflowError that might occur in the htmlcleaner when processing larger documents (especially those with a lot of block-level elements, such as large tables). This fix should also improve performance in all cases.
• Minor fixes (see SVN for all details).
