Updated parameter names.
Cell#row() now returns void to remove nasty API gotcha.

Very confusing to figure out why Cell#setActor isn't working when accidentally using the cell for the row defaults.
JSON minimal format, allow forward slash in unquoted strings.

Just not // or /*.
Don't insert character zero.

If a font actually has character zero TextField would go nuts.
Fixed wrong size used when scroll axis was disabled. Better pref sizes.
Fixed index out of bounds. Recalculate the line breaks when the size changes.
Added getButtonGroup.
