Remote control command to change window size

[gzotti]

This provides

• a scriptable command to change window size.
• a possibility to change window size via RemoteControl API

The main reason is interoperability with a program that utilizes Stellarium's Spout output.
The window size is no property that would else be synchronized over screens of different sizes.

The style cleanup (override etc.) should better be left as a separate commit...

[gzotti]

The whole thing is just a tiny little extra function. And as before, while doing something in a plugin, I change those override etc. keywords. Disentangling that into an extra commit, and squashing the Cleanup commit into the previous, is IMO a needless hassle.

Disentangling that into an extra commit, and squashing the Cleanup commit into the previous, is IMO a needless hassle.

Well, the point of disentangling is to make it truly separate, not to squash it. In fact, it wasn't even related to this PR so could be just pushed independently. And now anyone who gets pointed to this commit, say, by git-bisect, will have to study all these irrelevant diff hunks just to find the parts comprising the core of the change.
