Subject: [PATCH] Autocompleter: Adding support for a "regexp" option. If it
 exists, Ajax requests are done only if the token matches with the "regexp"
 pattern. Useful when using text areas where not every token requires
 auto-completion. E.g. regexp: /(#|:)(\w)*/ would activate Ajax requests for
 tokens that starts with '#' or ':'.
