Fix (tested patch)

Disk Costing shows an empty list for Terragen 3.4 msi installer

Problem comes from msi_dialog_vcl_add_columns function

This function exits if a width block is not a valid number

/* the width must be a positive number
         * if a width is invalid, all remaining columns are hidden
         */
this works fine in most cases BUT it should "continue" rather than exist to
manage case where the 1st field is used to specify "font" to be used

(see Orca extract from Terragen.msi table)

{ VSI_MS_Sans_Serif13.0_0_0} {116} {80} {80} {80}
