Wiggle parsing does not conform to spec

The wiggle parsing code in genomedata_load_data.c assumes the wiggle file will start with variableStep or fixedStep. The wiggle spec states that the first line must be a track definition line. If a standard wiggle file is presented, the loader will default to reading it in BED format and throw a large number of errors.

While you're at it, you might as well code in ignoring browser lines. http://genome.ucsc.edu/goldenPath/help/customTrack.html#BROWSER

Genomedata 1.2.2 now accepts track lines. Comment lines and browser lines are not yet accepted.
