Miscelaneous fixes and features as per UPDATES and KNOWNBUGS.

* Fixed $shuffle*() to respect extractw.
* Altered $rest() so that a negative first argument makes it a compliment to
  $right() in the same way that a positive arg makes it a compliment to
  $left().  This may conceivably cause problems for scripts.
* Spruced $joinstr() up a bit.  It now accepts any number of variables and
  respects extractw.
* Fixed an extractw bug in malloc_strcat_word_c while testing the above.

* Added $splicec() in functions script.
* Added /set dcc_dequote_filenames.  Perhaps this should default to off?

* Numerous updates/changes/fixes to DCC, functions, scripts, /EXEC, the
  new math parser, as per UPDATES and KNOWNBUGS.

One potential incompatibility is in the change to $open(). (as per UPDATES)

* New script features, cleanups, docs, etc as per KNOWNBUGS and UPDATES.

Another merge.

* $dccctl() changes as per UPDATES.
* Misc bug fixes as per KNOWNBUGS.

Yikes.  Merged to become consistent with HEAD.  Sorry for all the commits,
I'll be quiet again soon. :)
