GUI: Move ShowTypes enum to own class and file.

We are using ShowTypes around the GUI codebase so it makes sense
to have it in its own class. And the class also contains related
helper functions instead of scattering them around different
classes.

ShowTypes also contains the visibility settings for all the
GUI severities. Implementation in this commit makes ShowTypes
class to load the visibility settings when it is created. And save
the settings when it is destroyed.
