TKCalendarDayView.m : value stored to startMarkerHeight is never read

[klapaudius]

On line 520, when you do an analyse on project xcode found this issue : value stored to startMarkerHeight is never read

I've done those change on my working copy :

• line 432 : CGFloat startMarkerHeight = 0;
• line 520 : startMarkerHeight = [event contentHeight];
• line 520 : [event contentHeight];

In doupt, I didn't remove the whole line on 520.
