Updated token builder to use place holder images for maps in WYSIWYG editor.  WYSIWYG maps are now editable too.

As per comment http://drupal.org/node/1540804#comment-5909622, I have moved all markup to theme functions (apart from #preffix and #suffix form settings). I have also removed the width and height fields from the google map field in favour of this being set through CSS. Width and height are still available on the map token builder.

Moved as much inline JS as possible into static JS files and implemented Drupal.settings to pass values to JS from Drupal. As per comment http://drupal.org/node/1540804#comment-5900054

Removed ability to add unlimited google map field to content types. This can be done using WYSIWYG edit feature.

Output of map fields is now handled by a theme function and custom .tpl file as per http://drupal.org/node/1540804#comment-5900054

Added ability to give a label to individual map where unlimited google map fields are enabled. As per http://drupal.org/node/1540804#comment-5897612
