Vala version bump?

["Zeeshan Ali (Khattak)" <zeenix gmail com>]

Hi everyone,
  While Rygel currently depends on (and is tested with) Vala 0.8.0,
the minimum version of Vala on external deps wikipage[1] is 0.7.8 and
recommended is 0.8.1. Moreover, Jürg tells me that its the 0.9.x
branch that is intended for GNOME 3.0. I was wondering maybe we should
just bump the minimum version to 0.9.0 and recommended version to
0.9.1?
