very small improvements:

- mass_inserts does not requires keys to start at 0
- recent_cats categories are sorted by global_rank (consistency)
- removed warning from page_header.php (when included from redirect)
- added 2 template functions for plugins (get_var and concat_var)
- removed unused code from profile.php
- changed css width for tag selection (search page) from 55em to almost 100%
