#279049 reported by tormi: Use a valid variable for the author map marker. (You can now choose a marker by going to "configure" for the author map block.)

Fix minor issue with node type names. (This technically prevents XSS with content type names, but if you're giving out the ability to create / edit content types to people you don't trust, you have much bigger problems.)

#310357 reported by bobchristenson: Remove code that makes map/node 404 if there weren't any results.
#310365 reported by bobchristenson: Fix "map/nodes" typo in fieldset title.

* Reduce the number of variables used by the location map block.

Did some theme function renaming for gmap_location to be more in line with the 6.x way of doing it.

Fixed http://drupal.org/node/71251 and a rather ugly bug that was making the gmap_location.module's location setting feature not work properly.

Fix geocoding.  Still not really right.  For it to work, the map id has to be nodemap for nodes and usermap for users.

Will fix so it can be any arbitrary map name later
