support UNIX-shell-like tilde-expansions in file names and directories

 * expands to the value of $HOME (the env variable instead of
   the register which currently makes a slight difference).
 * supported for tab-completions
 * supported for all file-name accepting commands.
   The expansion is done centrally in StateExpectFile::done().
   A new virtual method StateExpectFile::got_file() has been
   introduced to pass the expanded/processed file name to
   command implementations.
 * sciteco(7) has been updated: There is now a separate section
   on file name arguments and file name handling in SciTECO.
   This information is important but has been scattered across
   the document previously.
 * optimized is_glob_pattern() in glob.h
