Prevent clustermarker from accidentally modifying the settings. Prevents a javascript error when using multiple maps.

Copy the string based map opts over. This will allow setting the draggable cursor at the map level, etc.

#802102 by rooby - When editing locations, after clicking to remove a marker new markers are not properly added.

RMT cache -- clicking on the same rmt marker more than once will show the previously fetched data instead of loading again.

#315236 by Bartezz, Fabianx, NigelCunningham, jcmarco et al. - gmap views that use ajax break when exposed filters are used.

(cherry picked from commit 9a79fc758f8a7f9d5b692d725722abfe2c98997f)

* Add Google Bar to search on map
* Add option for a marker tooltip field on gmap views
* Add option to highlight markers on mouse rollover event
* Add option to center Gmap on marker of node passed as argument in view
* Add option to highlight markers of node passed as argument in view

Add a way to bind controls that we aren't able to set the id/classes on from the Drupal side.

This lets us work around the fact that gmap_widget_setup() completely fails to work on CCK fields.

Example:
<code>
  $remap = array(
    'edit-field-latitude-0-value' => array('classes' => array('gmap-locpick_latitude'), 'id' => 'gmap-loc0-locpick_latitude0'),
    'edit-field-longitude-0-value' => array('classes' => array('gmap-locpick_longitude'), 'id' => 'gmap-loc0-locpick_longitude0'),
    'edit-field-address-0-value' => array('classes' => array('gmap-locpick_address'), 'id' => 'gmap-loc0-locpick_address0'),
  );
  drupal_add_js(array('gmap_remap_widgets' => $remap), 'setting');

  /* ... stuff copied from gmap_set_location(), etc... */
</code>

GPolygon.fromEncoded() and GPolyline.fromEncoded() don't take style arguments the same way as the regular constructors--styles have to be attributes of the encoded polyline/polygon object, rather than being arguments to the constructor

This fixes the annoying jerky / flashing marker when using locpick, and makes the whole thing feel a lot smoother.

Fix issue when bootstrapping multiple maps, jquery's each was calling the callback with a parameter and it was attempting to use it as a settings array.

Fixed it by isolating the callback.

Fix #155104 by Scott Falconer: Add "Zoom to cluster area" support.

Allow falling back to the default Clusterer marker if desired.

Allow entering larger numbers in some marker manager settings.

Allow choosing between the original and the new "zoom to marker area" behavior on Clusterer.

This file needs some serious work still, it will definately need the most work before dynamic bootstrapping works.
