Changes from CLC-INTERCAL 1.-94.-2 to 1.-94.-1

* Documented the sickrc file format and its extension mechanism.

* Updated to document the new extension mechanism and other changes
  in other parts of the distribution.

* Moved the INTERNET-specific bytecode, spats and register to
  internet.html, where it logically belongs.

* Some examples updated, some new examples.

* Some clarifications and updates on the INTERNET extension.

Changes from CLC-INTERCAL 1.-94.-3 to 1.-94.-2

* Created new package containing just the documentation, so
  that it doesn't need to be distributed with every version
  of CLC-INTERCAL.
