Link Limits plugin added

A simple but fairly effective anti-spam tool has been added to the server. If you activate the Link Limits plugin in your blog’s “Plugins” tab, comments will be rejected that contain more then 2 URLs or contain any BBCode (which does not work on WordPress and is frequently used by spammers attempting to post links). Because this plugin affects how comments behave, it is not activated by default, but is left as an option for each blog admin. That said, we recommend using it.
