[pio-develop] Toolbar in the editor

Hello all,

Some time ago, Micah Bunting wrote a patch to add a toolbar to the
editor [1] that was written by Brian Wellington. An earlier version of
the editor (Camato), written by Yusei [2] in Ruby, already contained a
toolbar.

The current version of the editor uses a combination of left- and
right-click to pop up a context menu to change the tile.
Camato uses a single selection on the long toolbars to specify the
modification to the tile. The proposed patch (toolbar.patch) has several
buttons that can be active.

At this moment it is not clear to me how the toolbar should work. I
personally like the context menus, because they allow me to modify the
board layout with a minimum of mouse movements, but I also like the
toolbar in Camato.

My personal workflow would be:
- Size the board to be of sufficient size
- Place the terrain tiles
- Add the dice numbers
- Add the ports
- Orient the ports
- Add nosetup nodes/hexes
(Certainly in any order when modifying an existing board)

This means that I would like to have the following toolbar groups on
which only one item is active (for the total toolbar):
- Modify only the terrain
- Modify only the dice numbers for the land tiles
- Modify only the port type and orientation for the sea tiles
- Modify the nodes/a complete hex for nosetup
Furthermore, I would also like the context menu still to be available
and also keyboard shortcuts (because that would minimise the mouse
movements for small changes).

Micah Bunting wrote the patch for his own needs, so he probably requires
another workflow.

I would like to receive suggestions, etc. When it is clear how the
toolbar should work, the patch can be implemented.

With kind regards,
Roland Clobus
