Introduced with PR #196 (commit d494fe189b)
This PR contains fixes for both issues reported by Lastique and
MarcelRaad. It makes PR #197 obsolete.
Removed obsolete dependency of test/qi/expectd.cpp on
mxc/qitoo/qitoo.hpp. Was reintroduced by mistake.
Created qi/detail/expectation_failure.hpp. It defines the
expectation_failure template as a common dependency of expect directive
and expect operator. Removed expectation_failure from
operator/expect.hpp.
Changed version.hpp to 2.54. I did not notice that addl file in the
first place.
As discussed with Joel de Guzman this PR introduces the expect directive
expect[] to spirit qi 2. PR includes code, test, example, and
documentation.

Here is what I did:
1. Added expect.hpp to home/qi/directives.
1a. Added forwarding header qi_expectd.hpp to include dir.
2. Renamed expectation parser (a > b) struct from expect to
expect_operator
to prevent name conflicts (expect directive uses struct
expect_directive).
3. Added expect directive to the common terminals
(common_terminals.hpp).
4. Added expectd.cpp to the test suite.
5. Added expectd.cpp to the examples.
6. Added expect directive documentation to directive.qbk. Crosslinked
expectation operator and expect directive docs.
7. Added expect directive to the index.idx file for index-generation.
8. Added expect directive to the qi quick_reference.qbk.
9. Added expect directive to the spirit reference card (tex, pdf)
10. Created a new section in the whats_new.hpp.
11. Changed spirit version to 2.5.4. Spirit index.html showed 2.5.2
allthough an 2.5.3 What's New section already existed. Fixed.
Improve QString integration in custom_string.cpp
There is an example of how to use Qi with Qt's QString as a custom string.
This is very helpful but it doesn't work in conjunction with the debug facilities.
The following patch fixes this by adding a couple of template specialisations.
