added page that shows bibtex for every reference in database, and added a random key generator (now a random key will be generated for the bibtex if the user doesn't supply one)
bibtex page textfield is now a little bigger
bibtex should now work with ÄÅÖ
generated key is now 4 chars long and letters are in upcase (akin to the examples)
