TURBO HERO 95: level one plays end to end

The first district of TURBO HERO is finished: you can start it, run it and
finish it without falling through anything.

Getting there was mostly arithmetic. The jump is short, the dash is long, and
every gap in the level is measured against exactly that pair. Change one and the
whole district has to be rebuilt, which is why they are locked now.

Next: a second enemy that does not come in threes, and the soundtrack.
