Patch [#27790] Drag and drop parenting in outliner

Submitted by Perry Parks (scuey)

>From the patch:
This patch enables drag and drop parenting for objects in the outliner.

Drag and drop is supported for a selection of multiple objects as well. Also,
all of the "special" parenting tasks (armature, curve, lattice) are possible
through the usual parenting context menus. For example, drag a mesh object onto
an armature and you are prompted for using bone envelopes, automatic weights,
etc.
