Add *.kcrash glob pattern to KCrash Report MIME type
Now that Bug 209041 is fixed, the temporary DrKonqi workaround http://commits.kde.org/kde-runtime/c4a72e847f4d3461f76205a0b732648d752063b8 is going to be reverted. Therefore the restored default extension should be recognized as KCrash Report. Let us keep *.kcrash.txt glob pattern as well for the time being to be compatible with older DrKonqi versions and to recognize crash report files created in the past.
The corresponding DrKonqi merge request: plasma/drkonqi!4 (merged).
