Internally product option values are separated by "," (comma). When one of
option values contains comma, like "3,5 ml" then that one value is saved as
two separate options and breaks down all option-related stuff. To solve this
option escaping problem once and for all I propose to use "inp_edit_minput"
control for option value input and store all that as one xml record (fields:
Values, Prices, PriceTypes).
