Setup RPATH for the python module (no need for LD_LIBRAARY_PATH on linux)
Do the reprojection without QGIS (just using proj4)
Tidy up the build of the Python module and installation

To build python module:
   python build-python.py [-debug]
To install c++ library and python module:
   python install.py [-debug]

Obviously, if -debug is specified, it will use debug version of Crayfish viewer.

No changes to the build of the c++ library.
Bumped version number to 1.1
Replaced plugin's install.bat/sh with more versatile python script
Reintroduced support for QGIS < 2 in the python plugin
