Minor update StormTac Web

Overflow fraction (Bypass).
The function of bypass in the box Reduction efficiency is now not only implemented for wet pond & wetland but for all types of treatment facilities.

Flow Volume and outflow.
Updated and improved function for calculating the treatment effect of wet pond and wetlands, parameter 6 Flow Volume in the box Reduction efiiciency.
The parameter now takes into account both the flow detention volume and the outflow, with higher treatment efficiency at higher volume and lower outflow.
If the detention volume 1 is removed because of severely throttled outlet for peak flows (and requests for lower total control height) the model calculates automatically the treatment effect of the detention volume 2 and the chosen outlet flow.
