Joshua Leung 98fd7c2948 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.

/* Outliner Searching --
Are we looking for something in the outliner?
If so finding matches in child items makes it more useful
- We want to flag parents to act as being open to filter child matches
- and also flag matches so we can highlight them
- Flags are stored in TreeStoreElem->flag
- Flag options defined in DNA_outliner_types.h
- SO_SEARCH_RECURSIVE defined in DNA_space_types.h
- NOT in datablocks view - searching all datablocks takes way too long
to be useful
- not searching into RNA items helps but isn't the complete solution
