…uncher (#844)

* allow sequencing_center to be passed as an optional input to demux_launcher

allow sequencing_center to be passed as an optional input to demux_launcher; this allows each job spawning a demux (uploader laptops, etc.) to set the sequencing center at upload time

* extend travis cache timeout

* make safe sequencing_center value passed to illumina.py, mention to avoid spaces in the DNAnexus applet demux_launcher

spaces may cause issues for the bash-like demux_launcher applet script
