Allow to JR to numeric constants

Browse Source 
Previously, JR was only allowed to labels (in the same section, or
different sections). When trying to JR to an address specified as a
numeric value, rgbasm would fail to calculate the JR offset (as it
doesn't know the final address of the JR so it can't calculate the
difference).

This patch makes rgblink calculate the offset whenever there is a JR.
