*Many* warnings in Firefox error console

[houchin]

When opening the main Round Cube window in Firefox, *many, many* warnings are shown in the error console. Some of them look like overzealous error checking (such as some of the "did you use = instead of ==" messages. However, others, such as noting that some functions don't always return a value and CSS errors) should be resolved. In all cases, it's probably worth it to resolve all the warnings, for the sake of clearer and cleaner and thus more easily maintainable code.

I see only css warnings, were are obvious because of use IE hacks etc.
