rework pkg-readme to conform to new template, update man.conf patch,
move man dir to Tcl's lib dir, properly preprocess man pages.
Bump major due to function signature change in tcllib.

Highlights of Tcl 8.5
* Speed: 8.5 now runs 10% faster than 8.4 with bytecode
improvements, object caching and reduced memory usage.
* Bignums: Tcl now supports arbitrary-precision integers,
which improves math operations on large integers.
* Safer interps: Tcl's powerful safe interpreter mechanism
now has improved control of time and command limits in
slave interpreters.
* clock command: More robust implementation of command for
specifying time, with significant l10n and i18n
improvements.
* dict command: New data structure that allows access to
data by value rather than a variable name, which is
substantially faster.
* Additional improvements: Faster list search, new and
improved mathematics procedures, anonymous procedures, new
ways to package Tcl extensions, Tcl-level custom channel
types, file and line location information for each
command, and more.
