Modedit: now shows a specific layers manager, which allows user to select the technical layer which is used when adding a new graphic text or outline to the current footprint.

Please, note the layer manager was already available in GAL mode, but is was the same as tne board editor, which is not good.
Now:
- In default mode or GAL mode, the look is the same.
- Only suitable technical layers (i.e. paired layers) are selectable from the layers manager (for special purposes, some other layers can be used, via the graphic items properties dialog)
