Make include-what-you-use happy with some files in source/graphics and
fix what needs to be fixed.
Ref: #8086
Signed-off-by: Ralph Sennhauser <ralph.sennhauser@gmail.com>
A new hotkey "hotkey.camera.togglebirdseyeview" allows to switch
between regular view and bird's eye (top-down) view.
When bird's eye view gets toggled on, the camera moves above the scene;
When bird's eye view gets toggled off, the camera moves back to the
default vertical rotation angle;
When bird's eye view is on, vertical rotation is disallowed.
Avoid cases of filenames
Update years in terms and other legal(ish) documents
Don't update years in license headers, since change is not meaningful
Will add linter rule in seperate commit
Happy recompiling everyone!
