----------------------------------------------------------------------
- superfluous and sometimes troublesome \unskip's were removed.
  Note that this changed the behavior of 'after upper' and 'after
lower'. Some user code may need to apply the new 'after upper*' /
'after lower*' options or insert an \unskip.
- even/odd page testing completely rewritten.
- some difference formulas were revised.
- new macros:
  '\thetcolorboxnumber', '\thetcolorboxpage',
  '\tcbifoddpage', '\tcbheightfromgroup'
- new options:
  'after upper*', 'after lower*',
  'center', 'flush right', 'flush left',
  'if odd page', 'if odd page*',
  'use height from group'
- library 'xparse':
  * new macro:    '\tcbsidebyside'
  * new options:  'sidebyside adapt', 'sidebyside switch'
