[kde-community] finding a clear vision for KDE - second draft for discussion

[Thomas Pfeiffer]

> KDE: control your digital life

and

> KDE - Be in control of your digital life.

are both fantastic taglines, but not really visions. 
They sound like KDE already allows that _today_, it's not talking about a goal 
for the future to aim for.

We should keep one of those as a tagline for KDE, one we can put on marketing 
material of all kinds, but I think it's a bit too short for a vision for the 
future.
