Prevent traceback using refresh param

This commit forces the 'refresh' param to be cast as a string to keep
things like 'refresh: 123' in a pkg state from causing a TypeError.
Prevent traceback using refresh param

Make the same change as was made in f0d1043 to pacman.py
Fix typo introduced in f0d1043
Add other sources of examples

I have a lengthy and growing "public" states repository that I build my various clients production on top of it.

some of them can be a little exotic.

SLES grain fix (#3275)

The 'os' grain in SLES 11 SP2 is 'SUSE  Enterprise Server' (two spaces).
Tried to fix this a couple days ago but didn't notice the extra space
after 'SUSE'. See the following:

SLES grain fix (#3275)
Fix Ubuntu bug in pkg.purged, pkg.removed states

17e35529 introduced a bug in which a nonexistant kwargs dict was being
referenced in the pkg.purge and pkg.remove functions. This is a blocker
for pkg.purged and pkg.removed states in Ubuntu.

I added kwargs to the pkg.purged and pkg.removed states, as well as to
each pkg provider which had a purge or remove function.

Note that this commit contains a lot of the same pep8 fixes that I made
in pull request #3311, so let me know if you want me to rebase once this
is merged.
Merge pull request #3310 from essentialed/develop

Added unittest support to rpm spec.
Make pydsl work with stateconf.

- Added implicit ordering to pydsl.(turned on via __pydsl__.set(ordered=True))

- Fixed a KeyError bug in stateconf renderer that happens during id renaming.

- The stateconf renderer now generates a no-op start state as the
  "first" state in a sls file.(enabled via -s)

- Made the stateconf renderer take high state input via the new -p
  option, so we can pipe pydsl output into it.

- Added more and fixed some test cases for stateconf and pydsl.
