Add a toggle to show only inorrect indentation

[krzyk]

Great plugin, but I use it mostly to get the color for incorrect indentation.

So I would suggest to add a toggle that would disable the normal coloring mode and enable just the incorrect indentation.
I know I can change the colors in settings and visually disable all other colorings but it won't save the added CPU usage of this plugin (e.g. when I scroll down a large file I can see how it slowly draws the rainbow indentation colors) hence the idea to have just a simple version with just the incorrect indent.
