Find and open menus through the spacebar search bar

For example searching for "edge" should also find the ctrl-e menu. Origin should find the shift-s menu. Unwrap should find the unwrap menu. Add should find the shift-a menu. And so forth. Click it and the menu opens.

Makes it easier to find stuff if you don't remember that particular keyboard shortcut and makes it easier to discover tools when you there are more ways to find the tools and find other similar tools.
