Update salt/modules/mongodb.py

Rectification of 'TypeError: port must be an instance of int' if using specified settings for Mongo.
Make PPA handling in apt-repo more robust

Take in the changes provided by ahammond and move them to the apt.py
module out of the pkgrepo state itself.

I've also included some changes that should make get_repo a bit
better and updates to better handle PPA style formatted names
in .absent calls

To avoid some odditiies any repo changes (add, delete, mod) will
do an explicit db_refresh()
Merge pull request #4115 from cedwards/system

basic support for reboot, shutdown, halt, etc.
Merge pull request #4116 from cedwards/PKGBUILD

updated PKGBUILD to 0.13.2 with minor fixes
Provide the master's version in pillar.data

This allows you to make decisions based on the minion version and
master version, for example, running pkg.install only if the
salt-minion is out of date

Grains would have the minion's version
Pillar would have the master's version
{% if grains['saltversion'] != pillar['master']['saltversion'] %}

Fix regex in _get_upgradable

We're not using the data after the version number in the apt-get output,
so don't bother trying to write an elaborate regex for parts of the
string about which we don't care. Fixes #4107.

Also made some pep8 fixes to make pylint happy.

Merge pull request #4126 from pengyao/develop

Add versions_as_list kwarg to version, list_pkgs

This commit adds the ability to optionally get the version information
in a list as opposed to a string. All package providers have been
updated with this (even though very few providers actually support
multiple versions of the same package), so as not to break pkg states.
