[IMP](axis labelSpacingMin) The labels' bounding boxes now better model the effective height of text; thus, now, the algorithms for label hiding and automatic tick count calculation work better; it was now possible to slightly increase the default labelSpacingMin for discrete axes, from 0.1 to 0.25.
[CHG](netbeans project) Changed to the new HTML5 project of NetBeans 7.3 rc1.
[CHG](cleanup) Removed files from the dist folder, that shouldn't be source controlled.
