[development] Reboot the PHP filter talk

This won't happen anyways because my intentions are to rename that module  
to php_eval and move the block stuff there, too. In other words: a module  
is rarely only a hook_filter. The block_visibility hook is already  
written. Will write the necessary form_alter stuff and merge the patch  
with Ber's this evening.
