Make right-clicking the omnibox with nothing selected select all (just like left-clicking).

Eat middle-mouse clicks on the omnibox to avoid tripping a CRichEditCtrl bug.

Original patch by Jared Wein (see http://codereview.chromium.org/2241003 ), r=me.

BUG=6873, 30134
TEST=Middle-click the omnibox, then try to click it (or any other UI element), and make sure the click has an effect. Select a portion of the URL and right-click on the omnibox. Notice that the selection does not change. Clear the selection and right-click on the omnibox and notice that the URL is automatically selected.
