Added new AisisCore Abstraction. Core Nav

The core nav has been abstracted in AisiGit and as a result
we now use this abstracted level of navigation to add more functionality
to AisisCore and Aisis-Framework.

[branch: dev1.2.6]
We now use numeric pagination for the transient

We now use numeric pagination for all index based loops,
this include achives, queries (custom) and transient loops.

We use regular prev/next for singular posts.
Fixed Page Shortcodes.

All Page short codes should render out properly. The short code dialog box
should look better. Feature Codes have changed, this has not been
reflected in the dialog for feature as of yet.

Feature Code js has been updated to reflect the new codes coming in.

We have added new styles for the feature codes and we have also added in
some media queries including hiding social icons and search when the nav
is collapsed.
