Added Multicolour BAC Visualiser + Added SoberTime stat

Please give me feedback as to whether you prefer this new multicolour
visualiser more than the previous single-coloured one. I think that the
multicoloured one will give users more info about what they drank and
when they drank it etc, plus what is contributing the most to their BAC
levels.
The visualiser will still have all new arcs turn red when the BAC is
above 0.1, indicating high levels and a warning to the user maybe to
slow down.

The SoberTime stat tells you at approximately what time you will be
completely sober, and includes hours, mins and AM/PM to provide the
user with the most useful information possible.

Unfortunately the multicolour visualiser timer method I have used has
now broken the instantCalc page, but this will be fixed ASAP. Let me
know what you think please.

Disregard changes to algorithmTest2, these were just tests I was doing
to try something out and do not affect the application at all as they
are not being referenced by any html.
