[2.1] & [3.0]: BBC - hr within table breaks table

[sbulen]

Basic Information

Using an [hr] tag within a bbc table can break table formatting, cause it to display the bbc code instead of acting upon it...

This is true in message bodies, in signatures, and in signature & post previews as well.

Steps to reproduce

1. Put this in a post or signature:

[table]
[tr][td][b][color=#0066cc]Slava[/color]
[color=#ffcc00][hr]Ukraini![/color][/b][/td][/tr]
[tr][td][/td][/tr]
[tr][td][sub]"Therefore, you should only allow people that you trust, implicitly, to have such access." -Douglas[/sub][/td][/tr]
[/table]

Expected result

Properly formatted table, with an hr that produces a line within the cell.

Actual result
