BibCiter

Over all, the most important update in the last version is that installation does not crack :P
I was noticed that the installation did not work. Actually, the installation (strictly speaking) did - at least this is my impression - and what did not succeeded was importing some sample data so BibCiter does not appear completely empty. I fixed this.

So, the new things this time are:

- added possibility to sort by year in bibliographies (useful to quicky glance the “range” of a bibliography)
- chaged the sorting option of bibliographies appearing in admin mode besides works: now by ID
- improved bibligraphy presentation filtering
- improved contact presentation filtering
- solved install problem

- improved the way search results are shown
- minor improvements in bibliography management
- fixed problem in category filtering

and the dumbest error ever. For those who downloaded v0.16 you know what I’m talking about.
