Drag & drop feature:

You now can drop a .blend inside blender window to open it.

Implementation notes:
- Added call to extract icon type for files. Code re-used from
  space_file
- External files that get dropped set icon types too.
  Drop box polls can check for this.
- Also enabled setting op-context for drop operators, this was
  needed to prevent filewindow to open.
