squashed my dev branch bigNetErrDisplay to test making code review easier; this code helps hgTracks display big network warnings and errors with a yellow background; it supports bigWig, bigBed, bam, and multiWig; In the case of multiWig, it can only draw the yellow background once at the beginning, and is limited to only drawing the first track that has a network error since overlapping multiple error messages would be unreadable
