Make Hyphenator config filterable

Hi @e2b, @odie2,
hyphenator_hook() (in hyphenator/plugin.php) loads the initialization script. It would be very useful to make $hyphenatorConfig filterable (something like apply_filters( 'hyphenator_config, $hyphenatorConfig );). This would allow developers to extend/change the configuration easily and would make requests like this one from @opticaldreams4u possible.

Also, you should use wp_add_inline_script().

Thanks!
