Indigo UI: Outline Palette

[tim_occ]

Hi all,

I've been thinking about some changes to the outline palette.

In my opinion, the current Outliner is missing some functions that would give the user a better overview of all objects.

New:
- Master pages and document pages are organized into sections
- Each page object shows information about the layer, locking status and visibility in PDF documents
- Visibility and locking status, as well as the object name, can be changed in the Outliner
- The filter filters the list by object types, such as text, images or vector path objects

Any other ideas about what is missing or would be useful?
