Adding a object interface to __salt__ & __pillar__ (pyobjects)

[borgstrom]

This is another suggestion from @mgwilliams. It adds an object to the
sls file scope named Salt, which dispatches its attributes to the
__salt__ dictionary.

For example, the following two lines are functionally the same:

ret = Salt.cmd.run(bar)
ret = salt['cmd.run'](bar)

@thatch45 think this could get cherry picked into 2014.1 as well?

I have plans to make pyobjects work for reactor files but I think we can save that for the next release.

[thatch45]

We tagged 2014.1.0 yesterday (packagers have been notified and we are announcing it on Monday), and we don't have pyobjects in 2014 at all since it was well past feature freeze. If you want this in 2014.1.1 let me know, but I don;t like adding things like this in point releases

[borgstrom]

No worries then, I misunderstood the PR when pyobjects was added -- I thought it was going to be added to 2014.1. If not then we'll just wait and it'll go out altogether.
