Dot at event

[vhlee7]

Description

Fixes issue #126

findDotAtEvent now finds position of dot at specific beats of a stuntsheet. I added a beat variable and the function checks for the dot's position at that beat.

There is an issue that came up where sometimes the mouse is not able to click/find the dot. To replicate, increment and decrement the beats and sometimes you will be unable to click on a dot.

I'm still getting an issue with the lasso tool:

I think this can be fixed at line 92 of ToolSelectMove
