Improve handling of elements containing raw text

While adding another test case from the goorgeous issues it became clear that
inline markup and html entity replacement were erronously applied to raw text
elements like inline code =foo=, src/example/export blocks, example lines,
etc.

To correctly handle those cases in both org and html exports a new
parseRawInline method had to be added.

Also some misc html export whitespace fixes and stuff
