Typo on wp-db.php: @war instead of @var

[mentel_br]

A typo on the comments for the declaration of $field_types on "wp-includes/wp-db.php", line 286 on the release 2.9.1 (file revision 12574)​, line 294 on trunk, file revision 12733​.

This typo may prevent the documentation to be generated accordingly.

The line currently reads:

	 * @war array

It should be:

	 * @var array

A patch is attached.

The patch for wp-includes/wp-db.php

Could probably use a description, though so could all of the wp-db vars.

In #11799 a patch contains valuable information regarding the docblock comments incl. missing var definitions and @since values.

(In [12763]) Typo fix. Props mentel_br. fixes #11921
