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
Merge branch 'temp-surge-fixup' into surge-fixups

Add selectional aux output
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.

Remove f77 version of step2
Fix up some function interface inconsistencies
cleaned up chile2010/maketopo.py
changed fgmax_read to take tstart_max and tend_max on two separate lines, other cleanup
changed fgmax_values to set value to large negative number in regions where h is 0
changed fgmax code to take only one min_level_check parameter rather than separate ones for arrivals and max since these were not both used properly.  Also renamed dt_for_max as dt_check since it is used also for arrivals.
