Started to rescind the name "skin", replacing it with "tool".  Did this in all
the places that normal users will see:

  - command line: --tool=foo (although --skin=foo still works)
  - docs: removed all traces (included renaming coregrind_skins.html to
    coregrind_tools.html)
  - in the usage messages
  - in error messages

Also did in in some places that I judged were unlikely to cause clashes with
existing workspaces:

  - in the header comments of many files (eg. "This file is part of Memcheck, a
    Valgrind tool for...")
  - in the regtests script
  - in the .supp files
  - in AUTHORS
  - in README_MISSING_SYSCALL_OR_IOCTL

Also update the AUTHORS file to mention Jeremy.

     If you absolutely cannot use dynamic libraries, you can try statically
     linking together all the .o files in coregrind/, all the .o files of the
-    skin of your choice (eg. those in memcheck/), and the .o files of your
+    tool of your choice (eg. those in memcheck/), and the .o files of your
     program.  You'll end up with a statically linked binary that runs
     permanently under Valgrind's control.  Note that we haven't tested this
     procedure thoroughly.
