Security: fix multiple XSS vulnerabilities + fix search tags with special chars

XSS vulnerabilities fixed in editlink, linklist, tag.cloud and tag.list.

Also fixed tag search with special characters: urlencode function needs to be applied on raw data, before espaping, otherwise the rendered URL is wrong.
