Add nested check for single time stepping
Bug fix in is_valid
Add set and get auxbc functions, add where needed

This commit seperate and adds functions for setting and getting aux
arrays from and to auxbc arrays.  These calls have also been added to
the stepping routines in clawpack as without them time dependent aux
arrays are not updated properly.  Sharpclaw was not modified.

Commit adds clawpack to the front of the visclaw imports in the plot

function (interactive plotting) is not done while using the html_plot
