Provide predefined workbenches

[SrNetoChan]

I really like the idea behind this plugin. The more I use blender, them more it seems that this is exactly the approach of blender interface.

It would be nice if the plugin comes with already some common workbenches. For example, digitizing. This would allow folks to understand it's usage.

After controversies about what should and should not be part of those defaults, I removed them early on ;) I am happy about suggestions though.

I think it will have more impact if people are offered with already some default workbenches. then they can change them at will. I am already working on a few workbench defaults that I can share with you.

I have other ideas that I would not mind to work\investigate:

1 - User Default should always be the one loaded on QGIS loading
2 - Changes in toolbars and panels should apply automatically to the active workbench
3 - The reset workbench button in that case should go back to the original workbenches
4 - This plugin could integrate the other one to create custom toolbars.
