 I noticed in a run with gridfunctions with only 1 timelevels that a
 significant amount of time was spent cycling timelevels. The attached
 patch makes the routine bypass a lot of code, if a grid variable only has
 1 timelevel.
 This reduces the total time spent in cycling timelevels from 417 s to 0.8
 s for a run of 32767 iterations.
