Defect DE1176: Can't create a new group in Crowbar.  This was caused by an intermitent race condition, sometimes location.href was being called prior to post completing basically short circuting it.  Moving location.href to $.post return function fixes this race condition.
Defect DE1176: Can't create a new group in Crowbar. Hide_group() was broken in IE as there was a uncommented console.debug call in that method which throws exception in ie.  Also changed hide group icon to server_delete.png instead of server_add.png.
Defect DE1176: Can't create a new group in Crowbar. Believe all issues fixed now, using DropTarget in a standard way for new groups and existing groups.  Believe this may have been a root cause in some of the problems we were seeing, doing the D&D in two different ways.

Defect DE1176: Can't create a new group in Crowbar.  Fixed drag and drop issues and race condition when adding to a group. [1/1]
Replace recursive_merge! with Chef's deep_merge!

recursive_merge! had a number of serious issues, worst of which was
that it did not recurse.

An exclamation mark was missing in the recursive call.  However the
interpreter never even reached this typo in order to result in a
NoMethodError, because the block passed to merge! was never used - b
is always a Mash and unlike Ruby's Hash, Chef's Mash ignores any block
passed to merge!  So in fact no recursion ever took place.

Other issues:

    if _old.class.kind_of? Hash.class

should have read

    if _old.kind_of? Hash

There should have also been a test when recursing that _new was a kind
of Hash.

In the case where _new was nil, it should not have overridden the
existing value.

Do not fail when new options lead to new subpaths in JSON

When a new option like scheduler/cpu_allocation_ratio is updated for an
old proposal, the JSON doesn't have the scheduler subpath, and it needs
to be created.
