Issue #1153032 by citlacom: Fixed Markers doesn't work in a view with the configuration: choose latitude and longitude fields.

Issue #1061566 by ankur: fix problem with rewritten field values for marker bubbles using token values from last result row of view for every row

Issue #1061566 by ankur: Add way to configure content to appear in bubble when clicking gmap marker in gmap format for view display

fix up gmap_location a bit.
change an old update to point to the issue queue -- not worth rewriting for d7.

Since location isn't ready yet, you have to use decimal fields to test it at the moment.

Original commits were for #679804.

  * 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

Also, fix a warning caused by neglecting to give the row plugin a chance to query.
Additionally, ensure that views knows we are capable of doing grouping.
The fix is based on the changes presented in #619884 for views.

Hopefully fix #371134: warning: Invalid argument supplied for foreach()...gmap_plugin_style_gmap.inc on line 172.

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.
