Loosen constraints on carpeting

This adjusts the carpet specification to fit what we used in SR2014, and
what we are likely to use in SR2015.  Removes mention of carpet tiles
and their colour.  Replaces this with a description of the physical form
of the carpet's surface instead.

Loosen up arena wall specification

Our existing arena design is somewhat incompatible with the number of
spectators that we expect in our knock-out matches.  Solutions to this
problem involve moving the audience back, and onto tiered seating, etc.

In order to make it possible to be seated/stood back from the arena and
still see robots that are at its edge, the arena wall will need to be
shorter.  Also, it seems highly likely that it won't be made out of white
hardboard.

So this patch changes the wall height constraint to be 100mm minimum,
rather than specified as 600mm.  This allows us the flexibility to adapt
the arena's construction to the situation it's in.  (e.g. it may be that
arena "A" has a higher audience capacity than arena "B", and so the
latter has a 'standard' hardboard wall, etc.)

This sounds like it leaves the arena markers hovering in free space.  Of
course, these can be supported by any structure of our choosing.

This creates the possibility that robots will snag on the edges of the
arena markers.  We could set the arena markers back from the surface of
the wall by 50mm to reduce this problem, and potentially move them up by
50mm to clear the minimum wall height.

Improve hyperref configuration

This sets various hyperref configuration options that make reading the
PDF more pleasant.  Significantly, this also prevents the PDF's
index/bookmarks from being limited to just the top-level section
headers.

Add link to intro spec'ing where latest rules are

Seems like a good idea to include a link to the webpage on which the
latest rules can be found.

Reset revision counter to 1

These are new, fresh rules.

Require rule clarifications to go via the forums

It's much more convenient if teams ask about rule clarifications through
the forums than via info@studentrobotics.org.  That way we end up with
fewer repeat questions, and don't have to bother the people behind that
email address as much.

Request online presence links via the forum

The online presence award section was requesting that teams email info@
with links to things.  It's better if they just post on the forum, as
then everyone can see etc.

Update the introductory paragraph for Capture the Flags

Remove rule allowing starting with a token in/on one's robot

This probably doesn't make much sense this year.

Remove rule about tokens starting upside down

That is not a thing this year.

Require flags to stay on the arena floor during a match

Change-Id: I465653acfadd03baf07fcfed12ea4ffaed93282e
Change "starting zone" to "scoring zone".

The robots don't start in the same area as they need to move the
flags into, so "starting zone" doesn't make much sense.

Not relevant this year.

Replace the arena diagram with a new one for 2015

This one is quite a bit cleaner.

Note: I'm defering decisions about 1/3 central tokens right now.

Remove the old background from the arena-markers image

This will have the new arena layout put in it at some point, but
that's probably not quite done for now so just leave this empty.
