Plasma 5.5 alpha

[Jonathan Riddell]

It was suggested to celebrate repo freeze I make alpha tars of Plasma
5.5 just to check we know what's being released so here's some tars,
please check it includes all the tars you expect and if you're
incharge of a new tar then check it contains the right stuff.  No
release is planned, beta is due in 2 weeks.
