improved: map markers ID multiplicity - a map marker now space delimits the ID field in the GEO micro format doc and takes on all of the sub-IDs so that a marker can light up when a mouse over occurs on either a single GEO record or as part of a group of GEO records
updated: hide element id="blog_list" when use clicks to add new blog post
changed: form target elements when creating a blog post should be 'lat' and 'lng'
nothing to do: markers need a mouse over title
update: small security fix - escape HTML that ends up in an info window
added: inline DOM fiddle methods for revealing the add surface form - similar to add blog post method
refactored: renamed a few variables so they can be used by both add blog and add surface
changed: map to pan instead of jump on blog click
