JabRef

What's new in this version:

Changed:
- We integrated the external file types dialog directly inside the preferences
- We disabled the add group button color change after adding 10 new groups
- We inverted the logic for resolving BibTeX strings. This helps to keep # chars. By default String resolving is only activated for a couple of standard fields. The list of fields can be modified in the preferences
- We moved the search box in preview preferences closer to the available citation styles list
- Changing the preference to show the preview panel as a separate tab now has effect without restarting JabRef
- We enabled switching themes in JabRef without the need to restart JabRef

Fixed:
- We fixed an issue where the preferences for "Search and store files relative to library file location" where ignored when the "Main file directory" field was not empty
- We fixed an issue where #chars in certain fields would be interpreted as BibTeX strings
- We fixed an issue where the fulltext search on an empty library with no documents would lead to an exception koppor
- We fixed an issue where clicking on "Accept changes" in the merge dialog would lead to an exception forum
- We fixed an issue where clicking on headings in the entry preview could lead to an exception
- We fixed an issue where IntegrityCheck used the system's character encoding instead of the one set by the library or in preferences
- We fixed an issue about empty metadata in library properties when called from the right click menu
- We fixed an issue where someone could add a duplicate field in the customize entry type dialog
- We fixed a typo in the library properties tab: "String constants". There, one can configure BibTeX string constants.
- We fixed an issue when writing a non-UTF-8 encoded file: The header is written again
