Support for Primaries and bug fixes

Added framework for help (not written yet). Added validation for Names
parameter, and marked Mandatory.

Added Primary and Save parameters, though the latter will likely be
moved to a different function.

Fixed bug with duplicate names in $list2 getting removed at the same
time by switching to removing them by their random (and unique) index
number instead. Added support for Primary selections and set extra
odd-match to process as a primary.
