UI: Add a text for not linked palettes

I had to use a trick with a disabled button because the template_id collapse when nothing is selected.

Here the operator new is not logic, so we cannot add the common "+ new" button.

UI: Hide cursor color for drawing brushes

UI: Move default color to main brush panel

Increase User number for palettes

Use Brush default color for cursor

If the brush has assigned a default color, the cursor must use this color, not the context default color.

Fix problem when change mode in brush color default

New default color for Brush

If the brush defines a default Palette and Color, when draw the color used is this and not the current context default color.

Still there is problem when change drawing mode from Line to Dots.

Merge branch 'blender2.8' into greasepencil-object

Cleanup unused code

UI: Change brush type icon and panel layout

Small modifications to some parameters and added text to type of brush.

Cleanup: Remove duplicated condition

Remove brush mode panel and add icon

The panel was not needed and was replaced by icons in the main panel.

Notice: I have reused standard icons, but maybe need custom icons in the future, but we will wait to the main redesign 2.8 interface task.

Merge branch 'blender2.8' into greasepencil-object

Change Brush names to organize alphabetically

As the panel is sorted by name, it's better to have names that keep brushes grouped.

Change Eraser icon depending of eraser mode

Remove unused and duplicate code

After moving bGPDbrush to Brush, some data is duplicated or not used.

Fix problem when change mode if no brushes

When chnage mode, create the default brushes if they are missing.

Fix problem with Brush Datablock icons

The icons of grease pencil brushes did not work because the poll return false.

WIP: more work moving datablock

All references to old bGPDbrush struct has been removed and basic functionality working again now.

Still the icons of the brushes are missing.

WIP: Fist step moving bGPDbrush to Brush datablock

Still a lot of work ahead, but this commit is to save the situation before remove bGPDbrush struct.
