Pbs custom

[jmccreight]

This branch allows "custom" overrides to PBS schedulers. For example

sched = wrfhydropy.PBSCheyenne(
    account='NRAL0017',
    nproc=2,
    nnodes=2,
    ppn=1,
    email_who='bob@dum.com',
    email_when='abe',
    queue='regular',
    walltime='00:10:00',
    custom={'-l':'select=1:ncpus=36:mpiprocs=36:mem=109GB+1:ncpus=36:mpiprocs=36'}
)

the above, instead of requesting 2 nodes each with 1 processor and default memory, would request 2 nodes both with 36 processors and the first with 109GB (large) memory.

It's a bit hacky, but c'est la vie. it's a power user option in an interface that aims to simplify.
