Fixed the 'Parameter file settings' dialog.

This dialog was killed by r11823 (https://mail.gna.org/public/relax-commits/2010-12/msg00123.html).

The problem was two fold. Firstly the settings were not being placed into the relax data store, but
instead in a copy of the relevant data structure. Secondly blank entries were fatal for both the
conversion to int and conversion back again.

Fix for the 'Parameter file setttings' dialog.

The columns could not be set to nothing, as the int() function was used to convert the value. This
would result in a ValueError. Instead the misc.gui_to_int() function has been written to perform
the proper conversion.

Bug fix for the Inputfile.__init__() method - the self argument always comes first!
