Upgrade Storagebibtex export
I regret that bibtex export is still producing invalid bibtex, because the cite key uses underscores to separate the components. (This was pointed out several times during the summer). It is straightforward to fix this by changing the underscore to a hyphen, and I would hope that it could be done for the next release.
The fields to export, and the format of the citation key, should be user configurable.
