Another day more UI improvements

The mascot has official been added, looking for names if anyone has any ideas throw them below.

Aside from that there's a dramatic improvement to the speed of the search function as well as the ability to search by code as well as name, giving a little more flexibility.

There's also been an update to the station boards, whereby the operator is now coloured correctly so that it's easy to see who operates the train. Not the most useful for stations outside of London but incredibly useful at a glance for stations like Stratford or Kings Cross.

As well as some minor font changes to make things a little more legible, things are coming along nicely.
