ENsetbasedemand() and ENsetnodevalue() - added ENsetbasedemand to allow changes to the base demands for each demand category. Changed behavior of ENsetnodevalue when used with EN_TANKLEVEL to also set the volume in addition to the initial volume (similar to how it sets the initial head and head. Without that, we can't reset the tank head and volume from RTX.
