Bug in LAK if lakes not active in first stress period

[langevin-usgs]

The attached model from Diganta Sarma demonstrates a bug in the Lake package. This is a MODFLOW-NWT model but it looks like the same issue could be a problem in MODFLOW-2005. In the model, lakes are not active in the first stress period so in GWF2LAK7RP, it skips to the line labeled 900. It then tries to compute the conductances for the lake. However, the lake leakances were never read and MODFLOW crashes in subroutine SGWF2LAK7UPW1RPS. It seems to me that the way to fix this might be to add a continue statement labeled 900 after the series of calls in GWF2LAK7RP where the conductances are calculated and remove the 900 label from the statement that has it now.
