Complete overhaul of css in an attempt to be more readible and maintainable.
CSS is now written with SASS which helps better separate/organize code, as well as
providing things like variables. Media queries (and the css in general) are far more
consitent now as result.

Changed admin page css to better match look of main site, while still being unique.
Removed a majority of inline css from html pages.
Includes a proper footer and site icons.
Made most pages responsive. Only notable exceptions are possibly players and matches?

Note: Alumni reunion form page has issues. Seems to break javascript for some reason,
and the "years played" section doesn't work responsively, yet.
