[Kst] kdeextragear-2/kst/kst/datasources/dirfile [POSSIBLY UNSAFE]

[Barth Netterfield]

CVS commit by netterfield: 

Fix for Bug 85211: kst consumes 100% cpu when plotting data with missing secondary files 

A field with a bad or missing linterp file now silently returns zero.

This patch also allows kst to read dirfiles with the first (or more) raw channels
missing.
