* Allow multiple locations for users and nodes.
* Fix marker titles and give them sane values.
* Add offset to make markers with multiple images work as expected.
* Rewrite gmap_location_author_block_view() to work similar to gmap_location_block_view().
* Remove hardcoded 'gmap_location_authorblock' mapid to match the behavior of the node block. (Reassign it in the macro if you need it.)

Add the ability to base gmap views off of arbitrary fields. Also add a way to specify the marker using a field.

As a side effect, this means that using a location_cck relationship will now do the right thing for a gmap view.

#350408 by pillarsdotnet: Selecting "Regenerate marker cache" does not reliably clear and rebuild the marker cache.
Changes:
gmap_regenerate_markers()

    * Pass TRUE to the gmap_get_icondata() function
    * Pass TRUE to the gmap_set_marker_titles() function

gmap_set_marker_titles()

    * Simplify and correct the caching logic

gmap_flush_caches()

    * Add an implementation of hook_flush_caches to ensure that clicking on the "Clear cached data" button from the /admin/settings/performance page also rebuilds the marker cache.

Add shape clickability.

Keep track of a per-map storage handler variable. It can be accessed if needed by adding a second parameter to the callback function.

Brown paper bag fix. I broke hyphenated mapids back in September and it took me this long to notice.

Fix #345269, noticed while helping George2 in IRC: Call node_view() instead of theme('node') to make stuff like CCK fields get output correctly in node markers.

#336995, reported by skyredwang: Disable caching for gmap_location blocks, because they do dynamic things.

Commit this while I'm in the middle of it because I'm really happy with it so far and I don't want to lose it. ;)

#330343, reported by fabio84 and also by epimeth in irc: Make script url valid again, I forgot that url() returns raw ampersands.

Let people pass map arrays to theme('gmap') without wrapping them in array('#settings' => ...). In theory.

* Remove references to mousewheel.js, clean up variable.
* Add support for Continuous Zoom, enabled by default.
* Add behavior flag for disabling Continuous Zoom.
* Remove workaround from may 2007 (rev 1.1.2.15) that was causing zooming problems.
