Should quote custom configurations that need it

[lithian]

If I add a new property to a component config that isn't a valid JS token (e.g. my-property) the designer doesn't warn me, and there isn't any way to change the property name too (or at last I don't find it).

It should be fine the designer is aware of this problem and quote the wrong property name.

Thanks for the bug report.

This was fixed in build #341.
