Support for SD.Next Control tab

[MysticDaedra]

In SD.Next the standard features of Canvas Zoom don't appear to function in the Control tab, only Img2img. This would be great functionality to have in the next update.

okay i dont think we will be supporting control tab anytime soon since they made the switch to using classes since that would cause me to need to support a class based system. and mannage state on my own. non of the canvas's have info about their state. (this does not mean that i will never find time to add support. but as of now i dont even know how to go about supporting the new updates.)

@daswer123 what do you think?
