test/manual/test_move_semantics.cpp: example and manual test case to demonstrate move semantics
test/manual/Jamfile.v2: added new target test_move_semantics
doc/ublas.css: added pre.screen class for code snippets, added p.credit class for thanks and credits
doc/overview.htm: fixed broken anchors and missing alt-attribute
doc/release_notes.htm: added new feature to release list
doc/options.htm: new page to document preprocessore switches (mostly copied from Wiki)
doc/index.htm: added link to options.htm

matrix.hpp: added move semantics
vector.hpp: added move semantics

Because for the bounded and c types, the move semantics don't have any effect, I think they should be disabled for now for those types, so that they don't promise something that they don't do.

Also in the options.htm, I would propose the description to read:

An immediate effect of this option is the elimination of the need for noalias in types <tt>vector<T></tt> and <tt>matrix<T></tt>, when assigned to the same type. This option doesn't have an effect on bounded and c types. Although it is rare, not all compilers support copy elision (that allows for move semantics), so a test must be performed to make sure that there is a benefit when it is enabled. A small demonstration and test can be found in test/manual/test_move_semantics.cpp
