Bugtracker mission fixes

So I've moved the runaway missions into the neutral directory because they don't seem to be a faction in and of themselves so I figured they best belonged in the neutral faction (though that does contain some none neutral missions too - for example the old lady mission which is only achievable in Sirius space...

I've also fixed the tutorial Communications bug in the google bugtracker, maybe a partial fix for the lack of autorefueling in the Joanne protection mission, also fixed the runaway mission (the second one) which completed as soon as you got to the first planet due to Lua being interpreted and instantly changing variables (it's a bug that wouldn't have happened in C I think) and finally, added a marker for Pas in the Shadow Vigil event until a player log exists (also something mention in a bug in the google bugtracker).

Note: The Joanne protection mission is hugely longer no in 0.6 than in 0.5.3 just because so many systems have been added in between, not sure if this was the original intention!
