Changed layout of index page and started on individual club pages

Instead of the accordion layout which is on the site now, I have changed
it to a more simple dropdown menu interface. The students and teachers I
asked preferred my design.
Individual club pages are not quite done yet, I still need information
for most of them. All the information on the pages now was taken from
the mini.html and the original index, so not everything has all of the
necessary information, such as room numbers or meeting dates/times.
Added content, fixed bugs, polished layout, and more.

Added content to all of the club pages that i got any information for,
however some clubs are still missing some or all of the information that
I wanted.
Also fixed some bugs which I found when the page was displayed at lower
resolutions.
Finally, I also made the second header an SSI for quicker editing.
Got rid of unnecessary code
Changed reminders box
Merge clubs into master
Removed "News" from navbar
Fixed some layout and coloration
