Subject: Add the ability to add new cylinders
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=c49d2439e85e0aafc353aeda35fb5a14721a49a7;p=ext%2Fsubsurface.git

Add the ability to add new cylinders

This is totally useless since you cannot actually *edit* the resulting
new dive yet, but we'll get there.  And this already conceptually shows
a capability that we didn't use to have with the old interface.
