* Added Parsoid config, and refactored code slightly to
add native Parsoid handlers for parser tags exposed
by this extension.
* Enabled parsoid mode testing on the test file.
* Added html/parsoid sections on a few tests.
* Marked rest of tests as wt2html and wt2wt only since
html2wt and html2html will fail without a html/parsoid section
and there is no real benefit to adding them to all tests.
* Added a couple tests to the known failures list:
- One is because of T299103.
- The other is because Parsoid always emits attributes in the
form <tag .. foo="bar"..> instead of just <tag ... foo ..>
Since Parsoid needs to accept this format that is present on
wikis, I added a html/parsoid section for this test and
added the failures to the known failures list.
