Check out latest version and pound on it

[Alexander Larsson]

I'm going away for the weekend, but when i come back i plan to release
version 0.40 as soon as possible. Only bugs that crash the program need
to be fixed before release. Please check out the latest version and
pound on it to see if you find any nasty bugs.

The line-arrow properties crash is still there. I'll try to track it on
Monday.
