add kmod.is_loaded to check if a kernel module is currently loaded.

this
  if salt['kmod.is_loaded']('aacraid')

now obsoletes my workaround:
  if salt['cmd.retcode']('lsmod |grep ^aacraid') == 0

in sls files

Make yumpkg module log locally to /var/log/yum.log

The addition of _YumErrorLogger effectively killed local yum logging.
This commit modifies the logger to behave more like
yum.rpmtrans.RPMBaseCallback, bringing back logging to /var/log/yum.log
while preserving the special error logging that this class initially was
written to provide.
Minor logging tweak

This just tweaks the order of when the minion logs certain things, for
consistency.
Add notes on yum.conf and syslog

Fixing the logging issues in 3b8b6de uncovered some interesting info
about how yum handles syslog. This commit adds that to the top docstring
for the yumpkg module, as it may prove useful to users.
Add some mirrors to pip install calls.
Initial implementation of git pillar

This isn't a particuarly pretty implementation, but it does work.

There are a few "gotchas" with this implementation-- since the pillar builder uses the local fileclient you have to have some directory which has all of the files-- to work with this i've set it up so you have to specify a branch+repo combination.

Ideally we'd need to do some work on the fileclient to add a new class which is something like "gitremote" that can then manage all of the file getting/caching/etc.
Update windows.rst

I think 2008 SP1 is needed. In my case it was crashing with return code 0
iadd some docs to mine.get for grain matching etc
