Phase for periodic sources and for non periodic sources

[lucabaldini]

[ximpol issue #104]

The phase cannot be assigned at the level of the source, but should be added in a second step, after the simulation is done. In fact all the sources (also the non periodic one) has to have a phase assigned (we don't know in real life which event comes from a particular source. Right now I have changed the old default value (-1) to random.uniform(0,1) for non periodic sources, but this is a quick (and wrong) fix.
