The CaptionButtons control spells Minimize and Maximize inconsistently

I was theming the CaptionButtons class and noticed that there is inconsistent spelling of “Minimize” (currently “Minimise”) and “Maximize” (currently “Maximise”), even in a PART name.

It would be ideal to stick with the US English version of the words instead of the British English version since those are what WPF is based on, and your pseudoclasses (:minimized, :maximized) and WindowState types are already using them.

Part Name

[TemplatePart("PART_MinimiseButton",   typeof(Button))]

Should be:

[TemplatePart("PART_MinimizeButton",   typeof(Button))]

There are other variables that need to be renamed in the CaptionButtons class source as well.

AutomationProperties.Name

The AutomationProperties.Name assigned in templates like in the Simple theme is using the British English version instead of the US English version.

Summary

This is a quick change but one that should be made for consistency.

@robloo - The changes in the PR look good.

This is a quick change but one that should be made for consistency.

I think this is also a breaking change, so should be done now or never.

@AvaloniaUI/core are we happy with such a PR at the current stage?
