Properly close the minimap buffer when quiting vim
Major update: added sync scrolling, proper closing, live update (including when typing)

One stupid pending issue: when invoking :Minimap, the active window becomes the minimap
window for a reason I do not understand.
Fixed the issue with minimap incorrectly being the active window

Thanks to Christoph Trassl for the tip!
Ensure the visible part of the buffer is centered in the minimap
isolate python code
