location 5.x-3.0-test3

Changes since DRUPAL-5--3-0-test2:

• #297913 by catch: Use province names instead of codes for autocompletion.
• #297968 by scottgifford: Map link should use latitude/longitude if available.
• #297978 by scottgifford, patch modified by me: Zero latitude/longitude sometimes displayed. I relaxed things a bit to allow ONE of the two to be zero.
• #297965 by scottgifford: Instructions for entering latitude/longitude are wrapped poorly.
• #305474 by becw: Add more countries to google geocoder supported list.
• Split location_search variables out from the main settings page, as they were confusing *ME*, which means that they were probabaly REALLY confusing the *users*.
• Fix XHTML non-compliance issues.
• Fix country overriding.
• Remove some dead code.
• Fix default value for 'additional' field.
• Provide some feedback for previously geocoded locations.
• Allow hiding arbitrary fields on display.
• Add the concept of "virtual fields" to fix the "Module declared field without empty default" error for good.
