Added slick-nav, applied when screen is small

Added:
1 /libs/java/slick-nav/
2  ^jquery.slicknav.js
3  ^jquery.slicknav.min.js
4  ^MIT-LICENSE.txt
5  ^README.md
6  ^slicknav.css

Reasons:
1-6 slick-nav looks like it will make navigation menus easy

Modified:
1 navigation.php : createNav()
2 index.php

Reason:
1 Using the menu template from slicknav.com to test out slick-nav
2 Moved the core.css to be the last loaded so that it overides
everything else.

Deleted:
1 /History/History.log

Reasons:
1 Decided not to use it, will just keep track of beforePush.log

Thoughts:
1 Nav Menu needs to have a style applied to it for tablet display and
desktop display.
