Add 'custom select' custom field

This patch adds a new custom field type ‘custom select’ (lack of
inspiration…).

What it does:

  • values can be selected from a list ()
  • the selected values are displayed with a checkbox (and can be
    removed by unchecking the checkbox)

A screenshot of this is attached.

Benefit(s):

  • it is easy to see what values are selected
  • it uses less space
  • adding/removing a value is easier

Downside(s):

  • values can only be added 1 at a time

(The custom field is based on EditCustomFieldSelect.)

Best regards,

Bram
