0.31 Balance and Bugfixes

Hi all,

The 0.31 release is a small bugfix and balance patch.

We've changed the gameplay slightly to give a reward when a level of buildings is completed. We felt like the game was a little bit on the challenging side and also we wanted to reward players better for completing a goal.

There are also a bunch of miscellaneous bugfixes, most notably a bug that prevented water from correctly spreading past calcifiers and conveyance ports.

Enjoy :)
