views integration module fixups (map not working, not updating lat+long details)

I have fixed a few issues with the views integration contrib module

• $_GET['edit'] does not exist for $_GET methods


• Refactored to use existing location_latlon_form() for generating the proximity map, this fixes a bug with lat/long not being updated when selected


• Fixed a bug with cache clearing of views - location_views needs to clear the *entire* views tables cache when a user submits the form if you expose your filter, so it can reprocess the form entries, i feel this is a shortcoming with views that it caches the form output of your handler so you can not set the #default_values of any form parts thereafter submission

hope this helps everyone!
