[PATCH] toaster: issues in import layer when clicking 'add layer'

From: David Reyna <[email protected]>

There were three issues in this one bug.
  1) The Add Layer button allows empty layers
  2) The internal XHR URL was wrong, which caused a hidden AJAX error
     and did not correctly complete the action nor disable the button
     after an add.
  3) There was a race condition between typing in the dependent layer
     select text box (which would normally disable the add button), and
     the typeahead pull-down selection (which would normally enable the
     add button). This forced the user to select the typedahead layer twice.
