Core errors are logged under INFO

[arisu3]

For example there are errors here but all messages are logged under INFO 1:

01:43:09:I1:TailFileToLog:WU588:Completed 400000 out of 2000000 steps (20%)
01:43:09:I1:TailFileToLog:WU588:An exception occurred at step 400000: Discrepancy: Velocities are blowing up! 24031 2 -17.6575
01:43:09:I1:TailFileToLog:WU588:ERROR:98: Attempting to restart from last good checkpoint by restarting core.
01:43:09:I1:TailFileToLog:WU588:Folding@home Core Shutdown: CORE_RESTART
01:43:09:I1:Unit:WU588:Core returned CORE_RESTART (98)

This is probably not the only instance. The core should communicate the log level of its messages to the client.
