Various plotting fixups for surge
Move track output to tick

This allows the surge calculation to use the same valout as the shallow
codes.
Update tick to GeoClaw base

Fix track output bug

The track output was moved into tick from valout to reduce the number of
duplicated routines in the surge code.  Unfortunately the initial
location of the storm was no longer being output.  This commit returns
the output of the track to valout, removes it from tick, and changes the
warning in the plotting from an exception to a printed warning.
