Dev2 feat parent node and path function

[bgro]

Regarding the discussion in #141 : with the proposed change by @meedstrom and these additions, I now get the following to work:

("x" "Capture text into node with the node path provided by a function `bg-node-path-query'"
 entry
 #'org-node-capture-target 
 "%?"
 :path bg-node-path-query 
 )

("Y" "Capture text into node and always ask for path, no matter what the default setting is"
 entry
 #'org-node-capture-target 
 "%?"
 :ask-path t
 )

("X" "Capture into a file with given id"
 entry
 #'org-node-capture-target

 "* %(org-capture-get :title)\n:PROPERTIES:\n:EMAIL:\n:PHONE:\n:ALIAS:\n:NICKNAME:\n:IGNORE:\n:ICON:\n:NOTE:\n:ADDRESS:\n:BIRTHDAY:\n:ID: %(org-capture-get :id)\n:END:\n"
 :parent-id-if-new "249506ab-d89c-4419-aecd-70d7c314ce36"
