MIKE BASIN hotfix 11-01-2017

This hotfix resolves the following issues:

1. The calculation of the updated LAV curve was numerically unstable when the new zero level is close to the old one for reservoirs type I, II and III. For that reason the update will be postponed to later time steps when the new value is too close to the old one, avoiding these numerical problems.
2. The routing of sediments had mass errors, resulting on negative values for the virtual sediment on reaches.
3. Numerical error in the calculation of the new zero level for the sedimentation of the reservoir (levels of current LAV curve were wrongly read as integer instead of doubles).
