convertToHtml : not covered bbcode #10

Hi,
I discover your parser.
I try convertToHtml() function.

Some bbcode are not covered by parser :

1. quote bbcode with parameters :
   [quote="username"]text[/quote]

('quote' bbcode with username variable ; quote bbcode may exist with several parameters, i.e. phpbb3 :

[quote="username" post_id=8850 time=152549378 user_id=2]

)

2 : attachments bbcode
[attachment=id]filename[/attachment]

I don't know if it has a general interest to support them... or a specific to some bb software...

Thanks for your work.

Best regards.
