Can't run gaphor on Dapper

[Steve Frécinaux]

I can't get gaphor running on Dapper. Instead, I get this traceback:

AttributeError: 'module' object has no attribute 'CanvasGroup'

I also cannot try with newer source package because libdiacanvas is too old for 0.8

Change source package name (gopher -> gaphor) and confirm the bug with Gaphor 0.7.1-1
