Timothy Guan-tin Chien 08741f30ed Bug 1460962 - Support customized built-in element in XUL r=smaug
This patch enables us to specify a custom element type with |is| attribute
or property when creating a XUL element. Because non-dashed names are valid
custom element names in XUL (bug 1446247), other checks has to modified
accordingly.

The checks I am settling with are
1) Forbids the custom built-in element names to be a non-dashed name.
2) Forbids the custom built-in element to extend a dashed built-in element name.

This also ensures the custom built-in element types don't take on the same
name as the element name it extends.
