Add generic popup message to editor (e.g. for error message popups)

Browse source 
Add `CEditor::ShowPopupMessage` function to show a generic message in a popup.

The message text and color are configurable with the `SMessagePopupContext` argument object.
Instances of this class must have a static memory location, as the message needs to be available after the `ShowPopupMessage` function returns, and the address of this object is used to uniquely identify it in the UI.
