A lot of exciting changes going into 0.7.0

So 0.7.0 is getting more than the usual amount of work for a new build.  The Squadron system is already mostly functional now.  Mostly UI work is still going into it.  The Player Info window is already done.  A bunch of minor fixes are also going in. 

Work has started on Trade Companies, but this build is going to go out before that work is complete.  So expect that to be working within a few months. 

This though will be the first build to be pushed to Steam for better access to beta testers.  Currently I'm just putting the builds in a self extracting archive and posting a drop box link, which will still happen when this build is ready.  This is problematic because the builds are quite large already, and will continue to get larger.  0.6.14 was 419MB.  When all the other terrains get added, we are probably looking at several GB eventually.  Repeatedly downloading new builds is a hard ask for some testers, especially when on metered connections. 

Steam though uses a diff like update process, where it only sends the changes from the previous build instead of downloading an entirely new build.  This will save a whole lot of tester hassle.  Relevant Steam keys will be provided to testers.
