Balancing changes for sliding

[Rusty-Box]

Right now, when jumping while sliding, Tux gains a little bit of extra speed which makes slidejumping quite OP.

Instead, when Tux jumps during a slide he will just not loose any of his current speed. If Tux slides down a steep hill and jumps. As long as he is in the air his speed will not get lower.

In summary When already sliding fast, jumping will allow you to retain that speed for longer. But doing the same when barely moving at all won't grand you extra speed out of nowhere.
