Fix #1586: Remove the SRIC Activity LED from the docs.

Remove the description of this LED in the table, and add a strike-
through on the diagram similar to the other things that are present
but not used.
Update SimplePie to fix warnings in PHP 5.4

Update SimplePie to the latest version in order to fix warnings in PHP
5.4.

The actual function of SimplePie has not been tested as I don't know
how, but it DOES make the warnings go away.
Install initial SR2014 event data, delete SR2013s.

This removes the out-of-data SR2013 date information from the front page
of the website. It also adds event pages for both of the currently
confirmed kickstart events, and the Surrey tech days.

Placeholders are added for other tech days and the competition dates,
currently all blank.

Add a link to the kit page.

This helps readers understand why the kit needs collecting,
as well as why we think it's important & what sorts of things
it will contain.

Fix #1737: Add a page documenting user-accounts.

This adds a page to the docs which explains how to get a user account,
what they are useful for & what to do if you forget something about it.
Also link to this page from the team-leader resources, so they can see
what we're telling the students about their accounts.
