gmap 5.x-1.0-rc1

To coincide with Location 3 RC1, here's GMap RC1.

Changes since DRUPAL-5--1-0-BETA6:

• Pamela Fox says to add overflow: hidden; to fix the "long copyright strings run out the left end of the map div" bug.
  http://code.google.com/p/gmaps-api-issues/issues/detail?id=308

  So, by popular demand, I'm adding a CSS rule for that.

  Tested in Seamonkey and IE6.

• 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.)
• #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.)
• #286159 by Cobalt747@drupaler.ru, gmap side. Add missing t()s.
• #307864 reported by chasz: Change mousewheel.js OFF by default to fix some warnings.
• Remove the old unused json callback.
  Remove the markerdata hack.
  Add a marker file generator and fix markers once and for all.
  Add a button to the settings page to regenerate the marker cache. (Please note that the Drupal 5 version submits the form as well. In D5 it's harder to make buttons that only do one thing.)
• Fix gmap alignment, which was still broken due to a missing space.
• Add an unloadMap function for debugging.
• Change how the google maps api script tag is generated to make it more obvious.
  Add 'hl' parameter to allow the map to translate itself. (Part of #314777.)
• Some work on gmap_taxonomy to attempt to resolve issues noted in [#295775].
  * Remove revision tracking, it doesn't work in D5 as taxonomy associations are NOT revisioned. Update required.
  * Delete marker associations properly.
  * Add a canary function so other modules can adapt to this change.
  * Views note: You *may* have to resave your location-related views. I had to change the join conditions slightly.
• Fix #316809.
