Improved syntax for markdown definition lists.

Definition lists are now more compatible with PHP Markdown Extra.
Resolves Issue #24.

+ You can have multiple definitions for a term (but still not
  multiple terms).
+ Multi-block definitions no longer need a
  column before each block (indeed, this will now cause
  multiple definitions).
+ The marker no longer needs to be flush with the left margin,
  but can be indented at or two spaces.  Also, ~ as well as :
  can be used as the marker (this suggestion due to David
  Wheeler.)
+ There can now be a blank line between the term and
  the definitions.
