Title: Issue #196: Prevent horizontal resize and prevent smaller vertical one.

I also tried toolkit.defaultChromeFeatures and various other things, but there almost nothing works to prevent resize :/
I wasn't able to prevent all kind of resize, but with this simple patch, only one kind of resize is still possible: you can get a bigger vertical size.
