Issue: url bb code parses as &quote;http://www

Fixed in the next release. Due to BB-Code tags being parsed after templates are parsed, some HTML entities like " were encoded before the tag could parse. This is fixed by unencoding " during the BB-Code cycle when they are used to wrap a tag option.

This change also fixes BB-Codes that use regular expressions for validation (like SIZE, COLOR, FONT, etc). Those BB-Codes were not parsing due to the encoded version of " not being detected by the validation expression.
