UI: Move brush mode to separated panel

This option has been moved to a separated panel because is too disruptive to have in the main brush panel.

Maybe in the future must be moved to new location, but we put here while we found a better place.

UI: Change Pin icon location

Fix error using different eraser modes

If the bursh was eraser, the brush was not using the eraser mode.

UI: Define pin icon for default eraser

Using pin button keep UI consistency better than a checkbox.

Merge branch 'blender2.8' into greasepencil-object

Avoid drawing with Eraser brush

If the current brush is eraser and try to draw, cancel the operator.

This could be activated with the D key and must be forbidden.

Implement brush eraser quick switch

This eraser switch works very similar to smooth sculpt brush in object sculpt mode.

When the user press Ctrl, the current drawing brush is replaced by the default eraser brush while hold the key.

After release the override key, the brush back to the drawing brush.

UI: Hide appeareance panel for Eraser brush

Create a full set of eraser brushes

Create Soft, Hard and Stroke eraser brushes.

Add new property Default Eraser

This property will be used when the eraser is enabled using fast switch key while drawing with other type of brush.

Merge branch 'blender2.8' into greasepencil-object

Add new Eraser modes to UI panel

Now there are 3 types of Eraser in UI panel:

Soft: Need several passes to clean stroke.
Hard: One pass, clean points.
Stroke: Clean all stroke when touch any point.

This modes were available before using modifier keys, but it was not easy to discover.

Cleanup: Move eraser brush draw to function and avoid duplicated code

Fix problem with Eraser cursor size

The problem was the internal red area was not using the same size of the external lines.

Change Eraser brush to use brush radius not global value

The old configuration uses a global user prefs value, but now must be the brush size.

Still need to fix the problem when resize size of the brush.

Enable right cursor for Erase brush

The cursor must show that you are using the eraser

WIP: New Eraser brush

This new brush is equal to the old eraser, but it makes the interface more consistent.

Still need more work to adapt all eraser features, limit other actions not related to eraser and brush switching.

Cleanup previous commit

Make more compact the code

Hide Draw cursor when Eraser is enabled

If the eraser is enabled, the little color dot used as cursor for drawing must be hidden and replaced by dash line circle cursor only.

Remove duplicate line

This line had to be removed in a previous commit.
