First skill automatically selected when backwards frameskip [BUG] [PLAYER]

[Wafflem]

Player V10.13.17

To reproduce:
1. Open a level that has more than one skill.
2. Select any skill in the skill selection panel that is not the first skill.
3. Press the backwards frameskip hotkey. The first skill will automatically be selected when this happens.

See GIF below as an example. After starting the level, I clicked on the miner skill. However, when I backwards frameskipped, it automatically selected the very first skill (the floater). This should not happen at all.

I've noticed this. I think Nepster's already looking into it, but I might have a look later today too. (I suspect there may be at least some connection between this and the bug with huge lag on backwards frameskips.)

Narrowed both this and the laggy backstepping to a commit somewhere between d3a829f and 6e98b26. Still trying to identify the exact commit responsible (and why).

EDIT: Both bugs originate from commit 711d915.

Found the cause and made a fix.
