fix renderer:plugin() signature

in 82d616353e4c3680d88f083eb6f88fe68de92904 we introduced passing the
raw match for syntax plugins to the plugin method of the renderer. This
was introduced for renderer plugins that might need access to the raw
syntax (like the table editor or WYSIWYG plugins). However the function
signature was never updated, making these additional parameter basically
secret. With strict standard this throws errors. This patch fixes this.

reintroduce a tiny bit of duplication

This reads some duplication in the from of haveing a Doku_Parser_Mode
and Doku_Parser_Mode_Plugin class which are basically the same but only
the latter extends DokuWiki_Plugin. This avoids the performance/RAM
problems mentioned in my previous commit. An interface keeps both
logically together.

With PHP 5.4 further deduplication could be done via Traits.

remove duplicate plugin code for syntax plugins

This makes Doku_Parser_Mode inherit from DokuWiki_Plugin which allows
for the removal of a bunch of duplicate code form
DokuWiki_Syntax_Plugin. This makes the code easier to maintain and makes
sure all DokuWiki plugins are actual instances of DokuWiki_Plugin.

However this adds a bunch of functions to the "normal" parser modes that
don't need them which could have performance/RAM implications.
