5 failing tests

[slyrus]

When one does:

(ql:quickload :cxml-stp-test)

one gets:

4 out of 246 total tests failed: TEXT.SERIALIZE, 
   ELEMENT.ADD-EXTRA-NAMESPACE.4, ELEMENT.COPY.7, ELEMENT.BASE-URI.

Notice I said 5, not 4, as pull request #1 fixes the with-attributes test, which still fails on the master branch.

Fixed:

• TEXT.SERIALIZE
• ELEMENT.ADD-EXTRA-NAMESPACE.4
• ELEMENT.COPY.7
• ELEMENT.WITH-ATTRIBUTES
• ELEMENT.BASE-URI

I added a list with checkboxes so we can cross off tests as we fix them.

For text.serialize, It looks we don't escape quotes when we serialize-to-string, but given the comment about "zzz CXML traditionally escapes quotes without good reason" maybe the current behavior is correct and we should just check for unescaped quotes.

in element.copy.7, the make-element call fails because the results of the format nil call are not a runes:simple-rod but rather some sort of optimized string. We can coerce it to a 'runes:simple-rod and the test will pass, but is that the right thing to do?
