harmonized all word-movement and deletion commands: they move/delete until the beginning of words now

* All commands and their documentations were inconsistent.
  * ^W rubbed out to the beginning of words.
  * Shift+Right (fnkeys.tes) moved to the beginning of the next word if
    invoked at the beginning of a word and to the end of the next word otherwise.
  * <W> (and <V> and <Y> by extension) moved to the end of the next word.
  * The cheat sheet would claim that <W> moves to the beginning of the next word.
* Video TECO's <W> command would differ again from everything else.
  With positive arguments, it moved to the beginning of words, while
  with negative it moved to end of words.
  I decided not to copy this behavior.
* It has been decided to adopt a consistent beginning-of-words policy.
  -W therefore differs from Video TECO in moving to the beginning of the
  current or previous word.
* teco_find_words() is now based on parsing the document pointer, instead
  of relying on SCI_WORDENDPOSITION, since the latter cannot actually be
  used to skip strictly non-word characters.
  This requires a constant amount of Scintilla messages but will require fewer
  messages only when moving for more than 3 words.
* The semantics of <W> are therefore now consistent with Vim and Emacs as well.
* Shift+Right/Left is still based on SCI_WORDENDPOSITION, so it's behavior
  differs slightly from <W> for instance at the end of lines, as it will
  stop at linebreaks.
* Unfortunately, these changes will break lots of macros, among others
  the M#rf, M#sp and git.blame macros ("Useful macros" from the wiki).
