pretty print the compiled tags

[weepy]

would it be possible to prettify the output html over several lines ?

riot.tag('song_footer', '<artist> \
  <photo></photo> \
  <name>{this.artist.name}</name>\
</artist>)'

It would be much nicer to debug.

As a temporally workaround, we could override HTML parser for this purpose.
But supporting sourcemap seems better option for me. Thought?

Riot@3.0.0 will support source maps for debugging so I will close this issue in favor of riot/compiler#56
