Various Changes - yet another large commit.

AisisCore elements and heleprs have all been brought to AisisCore to help
with #234 and #256 as well as Aisis Cores transient Issues.

We have updated the index to reflect the new navigation options, we can
style the navigation right from the loop options.

Fixed up the archive headers so that each header would grow and shrink if
their is a sidebar or not.

Cleaned up the custom loop to use default navigation.

Post template page now uses a transient loop instead of a query.

sidebar has been changed to use col-md-6 instead of span 6

Styles have been cleaned up and chnaged to reflect bootstrap 3.0

[tricket: #234, #256][Branch: dev1.2.6]
We are cleaning up the Framework its self.

We can now style the single pagination elements via the loop options
for both index and single (this is being cleaned up). This allowed us to
get rid of the single helper.
