[Sugar-devel] Removal of Activity Keep button

[James Simmons]

Simon,

All my Activities hide the Keep button.  I would like to be able to have
fully backward compatible Activities for as long as possible.  Everything I
wrote should work in anything from .82 to the present.  Hiding the button by
default would be better than just getting rid of it.
