HTML to BBCode tables and center

[brw]

Hey! Thanks for the very useful extension!

I noticed that the library you're using to convert HTML to BBCode doesn't support converting HTML tables. I was just wondering if you'd be interested in adding support for that somehow.

I also noticed that it converts elements with text-align: center to [center][/center], but in Gazelle (a private tracker web framework) it's [align=center][/align]. I suppose these things are different everywhere because there is no real standard, so you'd need user-facing options to enable/disable/modify tags accordingly which seems a bit difficult. But yea just something to take into consideration.

No time to improve this for now.

I plan to support converting HTML to Org-Mode in the future (without using a third-party library), and will probably improve BBCode at that time.

If anyone wants to improve BBCode soon, PRs are welcome.
