Calculate slot height based on the second row instead of first inner div. The reason we pick second row is to substract height of the first row (without border-top) to also calculate border-size. This should fix following issues:

* 1229: In "Week" and "Day" modes, selection doesn't work correctly if font-size != 14px
* 650: my events does not render correctly
* 1035:	On select click event selection start below mouse position
* 1149: strange behavior in selectable demo
