Modifying warning about negative allocation

In a global FG1 run (analytical spinup) with r7272, the following warning is printed over one million times per year:

WARNING 10b: numerical problem, residual is negative we are overspending
WARNING 10b: PFT, ipts:            8          43
WARNING 10b: residual,  -1.632571855481046E-011
WARNING 10b: allocation is being adjusted

grep -w 10b Debug/FG1.ORC2.r7272_22160101_22161231_out_orchidee | wc
4894592 36709440 275418160

It's a useful warning, but no one seems to be looking at it at the moment, and the debug files become a bit more difficult to manage. One solution would be to only write the warning once a year, but that would give the impression that it only happens once a year. Perhaps we should keep track of how often it happens at each pixel and what the maximum residual is? At the end of the year we could then write a summary that could be monitored.

This doesn't seem to be causing any other serious problem, as nothing is caught by the mass balance routines.
