Added a pre-write hook.

Added a hook to be run on the buffer after retrieving the bibitem but before saving. This can be used (for example) with bibtool to reformat the entries in the new buffer before saving it to the file.

Could you show an example hook (e.g. the one that you use)? I might then include it in the code (deactivated).

Here is how I use the hook. This way, whenever I fetch something using bibretrieve and then add it to a bib file, the file is automatically reorganised (sorted, keys rewritten etc) using bibtool and the bibtool rules file I use.

(add-hook
 'bibretrieve-pre-write-bib-items-hook
 (lambda ()
   (shell-command-on-region
    (point-min) (point-max)
    "bibtool -r ~/Bibliography/rules.rsc" t t "*Messages*")
