Merge branch 'gh-pages' into dev

Conflicts:
	index.html
	script.js
Added current time and time remaining (issue #11)

It was impossible to put both oriented left without messing with other
things (because HTML) so the remaining time is centered. Manan does not
like the time remaining in the period but I think it’s nice. People
like countdowns. Countdowns are good.
Merge branch 'dev' of https://github.com/HarkerDev/bellschedule

Update README.md
Clock Stuff

So Tierno gave me access to this main branch thingy. This is clock, and
some formatting. No need for the pull request anymore.
Change clock color to green

The previous color doesn't look too good, and the official harker colors
and white and green. In my opinion, this looks better.
Fixed Clock Positioning

Set the clock up so it does not push down the schedule, and aligned it
with the refresh button.
