Data tab improvements

1.  Default map layer to terrain
2.  default NOAA sites unselected-the stations are overwhelming and low priority for inclusion in a forecast
3.  Data set table: don't display PyID. Order should be:
Name Parameter Type ID.  URL can be hyperlinked to name.
4. Add PDSI and perhaps climate set selection to HUC when clicked.
5.  remove boxes in lower right for NRCC, PDSI, PRISM, etc.
