Add Geolocation to the content types. This adds several special case guards so we can still build & run whilst the full implementation is being worked on (in parallel)

(Some code taken from http://codereview.chromium.org/650180)

BUG=11246
TEST=Built & ran on all three platforms. Used geolocation & open content setting dialog.
