Minimap Usability

[ckitsanelis]

• Scrolling should be possible by rotating the mouse wheel, whereas zooming should be done by pressing the Control key while rotating the mouse wheel
• Minimap windowview should respond to changes to the Logfile (e.g. after a search & filter)
• When navigating the minimap, it should be possible to “jump to the next state change”​
• Enable scrolling by dragging the grey bar in the minimap Navigate by clicking in the minimap (see comment below)
• It would be useful if the user can inspect the value that underlies a color cell in the minimap by hovering over it with the mouse
• Adjust the width of the minimap depending on how many columns are visible

@ckitsanelis, not sure whether the second point (Minimap windowview should respond to changes to the Logfile (e.g. after a search & filter)) is still an issue, need to discuss.

About the 3rd point (Enable scrolling by dragging the grey bar in the minimap): when the minimap is zoomed out, the grey bar may become very thin, and thus difficult to click on in order to drag it. Also, when the minimap is zoomed in all the way, the grey bar has the same height as the minimap area, and then scroll-by-dragging it is not intuitive.
After some discussion with @lunalixxi, the decision is to implement another feature to allow easier navigation: by (left-)clicking somewhere in the minimap, the view will jump to that point.
