Avoid touching the geolocation object until needed

IE9 leaks when `navigator.geolocation` is accessed (see #461).  The goal of this change is to avoid that leak in builds that include the Geolocate control but do not use it.
Fix imageryProviders Bug

Sometimes imageryProviders is null so accessing providers.length on
line 255 causes a TypeError.

Instead of adding and removing the Google container, we just toggle
style.display. This also removes the unused rendered and displayed
properties of the cache.

Google Maps rendering bug on fresh reload. r=@kevbradwick (fix #925)
Account for the fact that touch devices have no mouse and therefore no last mouse position.  When "undo" is invoked in a mobile app, sync the meaningless last-mouse-position point to the last point in the digitized linestring so there is visible feedback that something has been undone.  Otherwise the last-mouse-position point is left at the point of the last tap on the map, which is unfortunately the location of the vertex that has just been undone, incorrectly implying that the vertex is still there.
Explicitly require the various Geometry types, as in GML.js, so listing OpenLayers/Format/WKT.js in a build config file is sufficient to build in these types.
