add /usr/lib in list of hints for XSD stuff

Reason
------
Debian policy allows development resources, such as the XSD files, to be stored
in the following private location: /usr/lib/<name> only. Therefore, adding
/usr/lib in HINTS and leaving ismrmrd/schema as suffix should be good enough.
put Boost_NO_BOOST_CMAKE into if(WIN32)
Fixes broken test for t_ndarraycontainer

MATLAB/FORTRAN indexing convention was used instead of C-style indexing,
provoking an out-of-bounds access to memory. This patch fixes the indexing.

fix spelling mistake picked up by lintian
adding ISMRMRD Image creation to Python example
add Numpy friendly accessor for getTraj

Allows to read the trajectory within Python using Numpy arrays. The
implementation follows what has already been written for getData.
Without this patch, getTraj() returns a valarray which Python fails
to translate into a meaningful data structure.
major rewrite of cmake files

Includes:
- use of global vars for more flexible handling of paths
- build ismrmrd_xsd library from xsd sources
- install still provides both the generated xsd source files in schema/
  and additionally the ismrmrd_xsd library in lib/
- on Windows, binaries are still generated using the xsd sources
- on OSX / Linux, binaries are linked with ismrmrd_xsd instead
add find mechanism for libismrmrd_xsd
fix for windows compilation
Change top level CMakeLists.txt to select Release mode build if build type not specified
enabling Boost_NO_BOOST_CMAKE option for all systems

this is necessary for Windows and RHEL <=6 systems and harmless on all others.
