- client/scheduler: standardize the FLOPS estimate between NVIDIA and ATI. 

Make them both peak FLOPS,
    according to the formula supplied by the manufacturer.

    The impact on the client is minor:
    - the startup message describing the GPU
    - the weight of the resource type in computing long-term debt

    On the server, I changed the example app_plan() function
    to assume that app FLOPS is 20% of peak FLOPS
    (that's about what it is for SETI@home)
