How to make a piano lid lift slowly

[palistov]

@Apjjm - yeah I didn't try it with a very large range of values. Perhaps the step value of .02 was a little too long.

@Your Computer - I tried using a looping timer to set the stuck state progressively higher, but the lid doesn't move at all when using that function -- I think it's only used for keeping the lever at a state once it has been reached.

Maybe I'll give it another later, but there's always the option of separating the lid and piano meshes and using separate entities. That's usually the approach I take, but I didn't dig too deeply into the issue.
