EasyEDA can't import devices without gates

[rossgrady]

This is more of an FYI -- I don't expect you to do anything in particular. But I just learned that EasyEDA online will throw a mysterious "null value is not permitted" if you have a device definition without a populated gates section.

For entirely logical reasons, your logo & mounting hole devices have empty gates sections. I tried just deleting those sections & importing, but still got the same error. I assume populating them with a spurious gate entry would be sufficient, but since I didn't need those devices, I just deleted them.

I'm sticking this here in case anyone else on earth is trying & failing to import this super-useful library into EasyEDA!
