Plan, Karbon: Disable the "Maintainer wanted" splashscreen for release branches?

[Friedrich W. H. Kossebau]

Hi,

I wonder if it is a go idea to have the "Maintainer wanted" splashscreen in 
Plan and Karbon also enabled in the 2.7 releases. People who still see some 
use in either programs surely will get annoyed quickly, and there is no option 
to turn it off.

So I would argue to enable that splashscreen always in master, but only in 
debug builds of release branches. That way it will reach those people who are 
kind of okay to mess around with code and building (and could also patch that 
screen away) but not annoy Joe User.

For releases we should (have) put that message rather (additionally) in the 
About dialog, I think now. We still can, either asking the translators for 
exception or keeping it in english (like the splashscreen, which is also 
untranslated).

What do you think?

Cheers
Friedrich
