Restore defaults
Re-enable fenced codeblocks
And syyntax colouring
Fix another regression
Fix a couple of tests
GenerateGenerate IDs for headers without a number appended to them, unless that header ID had already been used. Then, start adding numbers to keep the IDs

unique. Also fixes a bug where repeated calls to #to_html would generate different header IDs every time.
Another test
More breakage; this time with inline SVG
Fix handling of Raw HTML
Whoops! I must be going blind
Trailing content after raw HTML could be inline or block
Process Markdown in nested span elements
Handle whitespace in inline HTML text nodes more like other implementations
Resolve Issue 70: remove vestiges of old metadata syntax
Escaped content inside span elements
Just so we're clear on what's fixed and what ain't
JRuby Nokogiri brokenness
My bad: need colons, too
Some minor documentation updates.

Really, they should be completely redone.
Merge remote-tracking branch 'distler/nokogiri'
