Summary description: Semantic, keyval-based mathematics

Announcement text:

A clean-up update that should not change much for the end user. The most
important changes are:

* The commands \NewObject, \NewVariableClass, \NewSimpleClass, and
\NewSymbolClass now check whether the command name is already defined and, if
so, issues an error. In casesomeone wants to override this behaviour, commands
\DeclareObject, \DeclareVariableClass, \DeclareSimpleClass, and
\DeclareSymbolClass have been added.

* Some internal changes have been made which should allow issue-free use of
active (and math active) characters as names of classes and objects. Previously,
this was possible, but the system could not properly distinguish between
<character> and \<character> as object or class names.

* The deprecated class types Cohomology and Delimiter have now been removed. So
has the key "degree default" which was defined to be equivalent to "sep d".

* The stripsemantex ID markup commands have been changed from \SemantexIDcommand
to \SemantexID. This has required some changes in the names of commands in the
.semtex file.

* A section 12.4 has been added which shows how to create a binary operator
command that can also be applied to n elements.
