Subject: Added parser for definition lists, derived from reStructuredText
 syntax:

term 1
    Definition 1

    Paragraph 2 of definition 1.

term 2
    There must be whitespace between entries.
    Any kind of block may serve as a definition,
    but the first line of each block must be indented.

terms can contain any *inline* elements
    If you want to be lazy, you can just
indent the first line of the definition block.
