Fix warning when select a object not GP

The onion skin panel needs a grease pencil layer.

Cleanup: Operator properties for "GPENCIL_OT_multiedit_toggle"

* RNA_int -> RNA_boolean
* Rename "lines" to "toggle_visibility", as the previous name was ambiguous

Cleanup: Change the "back" parameter on GP editmode toggle operators from int to bool

It should have been a bool all along. However, it's debatable whether we should
even have this property to begin with, or a bunch of operators...

Fix: Re-enable toolshelf panels for GP tools

We will convert the UI later, so it can stay like this for now.

Cleanup: Simplify logic

Cleanup: Remove the old "total palettes" entry from the "Information" panel

Reshuffle order of panels in Propertes Editor -> Data, so that Datablock vs Layer settings aren't as mixed up

Fix compiler warning - comment within comment

Cleanup: Remove unused and change comments

Color PIcker use list of materials not object materials

Now, the list shows all grease pencil materials and not only the materials of the active object.

If the material selected is not in the active object material slots, the material is added automatically when draw.

Cleanup: Rename function

Cleanup: Remove unused parameter
