chemfig v1.4

- many bugs are fixed
- the private character in the macro name is no longer "@" but
  becomes "_" and the prefix of private macros is now "\CF_"
  IMPORTANT: this implies for advanced users who have used private
  macros to rename them
- all old macros obsolete for more than a year are no longer
  defined and will throw a compilation error if used:
      \setcrambond, \setatomsep, \setbondoffset, \setdoublesep,
      \setangleincrement, \enablefixedbondlength,
      \disablefixedbondlength, \setnodestyle, \setbondstyle,
      \setlewis, \setlewisdist, \setstacksep, \setcompoundstyle,
      \setarrowdefault, \setandsign, \setarrowoffset,
      \setcompoundsep, \setarrowlabelsep, \enablebondjoin,
      \disablebondjoin and \schemedebug
  From now on, the macro \setchemfig{<key>=<<values>} should be used
  to set parameters
- the syntax \chemfig*[][]{} is no longer accepted and becomes
  \chemfig[<keys>=<values>]{<molecule code>}
- the syntaxes \lewis[<coeff>]{<code>} and \Lewis[<coeff>]{<code>}
  are no longer accepted and become \lewis[<key>=<values>]{<code>}
  and \Lewis[<key>=<values>]{<code>}
