As logical extension of the ability to add bookmarks and gas changes this
adds the ability to remove (any arbitrary) event that happens at the mouse
position (specifically, that is within +/- six (scaled) pixels around the
x-position (time) of the mouse). That's the same width that the triangle
marker occupies which was moved to be centered around the event time in
commit 5752e9742e86 ("Finetune event triangle position to have the top
point at the event time").
Fixes #60
