fix(watcher): use ASCII-only comments/log strings (IronPython 2.7 syntax error)

Browse source 
0.4.1 used em-dashes (--) in three log strings and one docstring line.
IronPython 2.7 (CODESYS scripting host) rejects non-ASCII bytes in a
source file unless an explicit encoding declaration (PEP 263) is present:

  Microsoft.Scripting.SyntaxErrorException: Non-ASCII character '\xe2' in
  file ...\watcher.py on line 225, but no encoding declared

Replaced em-dashes with ASCII '--' and bumped WATCHER_VERSION to 0.4.2.
File is now ASCII-clean throughout.
