[fixed] Auto rotate and missing delay option

[tkbd]

Hi!,Hank.
In any case for value of angle , the initial speed was slow (In my Mac enviroment too).
And,You can change the rotation speed up or down with Push + or - key while Auto Rotation.

I have reported a bug relate to auto rotation earlier and it fixed.
To speed up for auto rotation makes app freeze.(Wings3D forum)
Delay option abolished after that,but I don't know why.
