Issue: XenForo 2.1 Table Support

VaultWiki already supports switching to the XenForo TABLE syntax, provided that you understand that it would break any existing TABLE BB-Code uses, and/or renaming the VaultWiki TABLE BB-Code so that both can be used.

What remains to be done is the following:
- Automatically disable the VaultWiki TABLE BB-Code if installing for the first time and XenForo >= 2.1. Upgrades would not be affected, so that the syntax change doesn't break existing content. Instead, the following will probably apply to upgrades:
- If the VaultWiki TABLE BB-Code is enabled over the XenForo 2.1 BB-Code and shares the same name, attempt to use the Froala buttons intended for the XenForo variant in order to style the VaultWiki variant.

This is the same approach that we took when vBulletin introduced ckEditor TABLEs.

Support added in Alpha 2.

- If VaultWiki is installed for the first time in XF >= 2.1, the TABLE BB-Code will use a different tag name.
- If VaultWiki's TABLE BB-Code has 'TABLE' as its tag name in XF >= 2.1, the Froala buttons can be used.

Is it simple to completely disable VW table code AND function?

Yes, as stated above:
