Eric J. Korpela a5a6f693cd - Implementation of automatic credit leveling for cpu based projects that
wish to use it.
- The script calculate_credit_multiplier (expected to be run daily as
      a config.xml task) looks at the ratio of granted credit to CPU time 
      for recent results for each app.  Multiplier is calculated to cause 
      median hosts granted credit per cpu second to equal to equal that 
      expected from its benchmarks.  This is 30-day exponentially averaged 
      with the previous value of the multplier and stored in the table 
      credit_multplier.
- When a result is received the server adjusts claimed credit by the
      value the multiplier had when the result was sent.

Eric J. Korpela 70baf36e93 - Added database table credit_multiplier and script to be run daily
(calculate_credit_multiplier) to determine what factor to multiply
   claimed credit by before insertion into the database.  Changes to scheduler
   to implement have not yet been checked in.
