Remove context menu on touch devices

[1nf0rmagician]

Summary

A long touch interaction triggers scrolling and contextmenu events. As the context menu event in the resource and products tree prevents defaults (to show a custom context menu), also the scrolling default behaviour is removed. To allow scrolling on touch displays we remove the context menu functionality on touch devices. All options from the context menu have been available on the toolbar before and still are.

When they are already in the toolbar - why providing it in context-menu too? Nevertheless, a good change, thank you very much, now the trees can be operated on a touch device again.

I can test it on a touch device later and give you feedback.

When you have a mouse you can use the context menu to call the actions on not selected products. Keeping the details of the current product in focus
