redefine reference check options

This patch correct the meaning of the reference check configuration
options. They become more logical.
  refcheck    boolean   Enable/Disable the reference checker. If set
                        to '0' the existence of references is not
						checked and vica versa.
  recshow     int       defines how many references should be displayed
                        If set to '0' no references are shown at all.

This meaning is more logical. The first parameter switches the checker
on/off and the second would be set, if the user wanted to see where the
references are and how many should be displayed.
