Major change in the way ordered lists are handled:

+ The changes are documented in README, under Lists.
+ The OrderedList block element now stores information
  about list number style, list number delimiter, and
  starting number.
+ The readers parse this information, when possible.
+ The writers use this information to style ordered
  lists.
+ Test suites have been changed accordingly.

Motivation:  It's often useful to start lists with
numbers other than 1, and to have control over the
style of the list.

Added to Text.Pandoc.Shared:
+ camelCaseToHyphenated
+ toRomanNumeral
+ anyOrderedListMarker
+ orderedListMarker
+ orderedListMarkers

Added to Text.Pandoc.ParserCombinators:
+ charsInBalanced'
+ withHorizDisplacement
+ romanNumeral

RST writer:
+ Force blank line before lists, so that sublists will be handled
  correctly.

LaTeX reader:
+ Fixed bug in parsing of footnotes containing multiple paragraphs,
  introduced by use of charsInBalanced.  Fix: use charsInBalanced'
  instead.

LaTeX header:
+ use mathletters option in ucs package, so that basic unicode Greek
  letters will work properly.
