Restructured the plugin system. Multiple plugins can bind to the same hook now (not available for variadic hooks yet!) The parser is now benchmarked. The bench_round4 is run with both plugin_markdown and plugin_bbcode enabled. Added a benchmark for the BBCode plugin. Moved some of the template writing logic into a more generalised function. URLs are now recognised by the system and linked. Converted more custom errors into LocalError calls. Faster and less bandwidth intensive Emojis on Edge. Fixed a bug with replies not working.
