allow for regular focus patterns to be used when using "focus patterns" option
Created originally on Bitbucket by v01d (Matias N.)
It would be very nice if it were possible to choose between default focus patterns only and custom ones (already present with "focus patterns" option).
Having the same set of "one point only" focus points usable from this function allows quick selection using arrow keys without requiring pressing the focusing point selection button, while retaining the default set of focus points (which I rather use, instead of the custom ones).
On 550d this is quite annoying since it requires: a) the shutter button to be half-pressed b) pressing focus selection button then, but before exposure reading expires. If the time expires, you must press the focus point selection button again.
