Rework Data -> Statistics dialog, add WithReplacement and KeepOrder

Browse source 
* Add "With replacement" checkbutton
  * checked: WR (with replacement, put back after draw), larger
    sample size than population size possible
    * mutually exclusive with "Keep order"
  * unchecked: WOR (without replacement, do not put back after
    draw), sample size limited to population size
    * automatically unchecked for "Periodic" samples

* Add "Keep order" checkbutton
  * checked: samples are drawn in order of population data
    * WOR method mutually exclusive with "With replacement"
    * automatically checked for "Periodic" samples
  * unchecked: samples are drawn in random order

* Limit "Sample size" and "Period" input fields to size of
  population for all WOR methods
  * when limiting, increment "Sample size" and "Period" up to
    their last known value when enlargening the population size

Previously, for "Periodic" samples the "Period" field was never
limited, which for populations of smaller size makes no sense.

The new recent implementation for "Random" without "Keep order"
and without "With replacement" set (WOR) strictly needs "Sample
size" limited to population size.
