#17 Date Input Enhancement as pull-downs

[Anonymous]

All date entries need to be turned into pull downs
where feasible.

Year will require some calculation and may not best be
a pull-down in all places - i.e. Join date year can't
be older than the club but birthday can realistically
go back 100 years.

Month can easily be a pull-down for all.

Day range will need to be calculated from month (and
year for February?) (via javascript?). Definitely at
leats validate day against month via javascript.
