messagewidget: Update docstring (signature)
messagewidget: Add TODO comment
minimap: `moveable` => `movable`

For consistency with e.g. instance.movable as used in this very method.
minimap: Small refactoring

Only calculate what used to be `movable_selecteds` where necessary.
minimap: Readability (less indentation for tooltip code)
minimap: Fix docstring
minimap: Alias for `self.minimap_image.rendertarget.addPoint`

Easier to read that way.
minimap: Line length
minimap: Remove unneeded line continuations

... because all of this code is commented out anyways, nothing changed.
