Add information for the first Southampton tech day

Patch Set #2: More colon

Change-Id: Iea384dd2de557e928c92cd983446b9f027606c1b
Simplify the creation of the AUTHORS file.

Presumably shortlog -sne didn't exist when it was created. This
creates the same output as the previous incantation, but avoids
using the complex awk command as git now does the counting for us.

Fix tenses on ECS internships

These happened some time ago.
Close a couple of unclosed tags
Add *.pyc to .gitignore

After running the tests various .pyc files are created, it makes sense
to include these in the .gitignore file.
Bring about/how_to_help slightly more up to date

No more references to the exciting upcoming 2010/2011 year.

Patch Set #2: Mention the University of Surrey
Patch Set #3: On second thoughts, avoid the branch list

Change-Id: Iec062e2fcbd3a39a0d12759300a8c2b2f64228e3
Add paragraph about already connected tablet

If the tablet is connected to an access point before the robot is turned
on, some fiddling is required.
Draw a diagram of the v4 power board

The intention is for this to illustrate where the connectors, LEDs and
other items of note are on the board, much in the same way as the
previous power boards documentation.

While I posess very few artistic skills, I this is a reasonable first
revision. Currently this is not linked to by any part of the website.

Patch Set #2: Make SVG standards-compliant (and actually render)
