Revert followup change for #337585 -- the only thing an empty macro should return is the autogenerated id.

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

Fix #337585 -- Behavior flags on macros weren't using the site defaults. This most often manifested as missing "nomousezoom".

Fix #703480, patch by dnotes: Brown paper bag fix in gmap_module_invoke: Don't nuke the return value repeatedly when cycling through hook implementers.
Fixes an issue where all the behavior flags disappear.

Move gmap_views_gmap preprocess function to gmap.module to work around caching quirks seen in the wild.

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.

Original commits were for #679804.

Renamed translations template file gmap-module.pot to gmap.pot and updated for current version of gmap

Fix #582934, patch by me, rerolled by pivica and hutch: PHP 5.3 compatibility for hook_gmap(). (Manual backport)

* 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

Fix #676108. Original patch by greenSkin, heavily modified by me to hopefully maximize compatibility.

In theory, this should work in both keys_api and keys now.

Stop confusing the marker system by blindly wrapping marker.text in a div, even
if it didn't exist.

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>

HOPEFULLY it will work okay.
The reason I was reluctant to change this is the interactions between drupal_add_js()
and hook_filter(), described at
http://mostrey.be/hookfilter-versus-drupaladdjs

If anyone has troubles with macros after this change, I will have to revisit gmap's filter
stuff.

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.
