Numerous bug fixes.  See description.

Bug Fixes:
-wbs.edit: Data packaged properly so that it can be saved back to
database.
-wbs.nav_action: function_save_array is now set properly (in the sense
that it works now...have to namespace the local variable to set it for
some reason).

Bugs:
-wbs.nav_action: # of updates for each WBS is doubled after doing an
archive on the current working copy of the charts.
-wbs.chart: After editing a schedule node, charts did not update to
reflect the change.  Investigating cause.
-wbs.msa: event date includes time.  This should be omitted as time is
not a factor in module.
