single_datetime 8.x-1.6

Added several new features, most important are: theme select, inline display of date selector and limit calendar by date.

Note, code for Date Range widget had received small changes. To avoid duplication of code (settings form, summary, etc..), class SingleDateTimeRangeWidget extends SingleDateTimeWidget (before was DateRangeWidgetBase).
