A few changes in the build mechanism and the file structure so scons can build release tar files:

  * paso/src/Solver has been moved to paso/src 
  * all test_.py are now run_.py files and are assumed to be passing python tests. they can run by 
    scons py_tests and are part of the release test set
  * escript/py_src/test_ are moved to escript/test/python and are installed in to the build directory 
    (rather then the PYTHONPATH).
  * all py files in test/python which don't start with run_ or test_ are now 'local_py_tests'. they are installed i
    by not run automatically.
  * CppUnitTest is now treated as a escript module (against previous decisions).
  * scons realse builds nor tar/zip files with relvant source code (src and tests in seperate files)

the python tests don't pass yet due to path problems.

+ NEW BUILD SYSTEM

This commit contains the new build system with cross-platform support.
Most things work are before though you can have more control.

ENVIRONMENT settings have changed:
+ You no longer require LD_LIBRARY_PATH or PYTHONPATH to point to the
esysroot for building and testing performed via scons
+ ACcESS altix users: It is recommended you change your modules to load
the latest intel compiler and other libraries required by boost to match
the setup in svn (you can override). The correct modules are as follows

module load intel_cc.9.0.026
export
MODULEPATH=${MODULEPATH}:/data/raid2/toolspp4/modulefiles/gcc-3.3.6
module load boost/1.33.0/python-2.4.1
module load python/2.4.1
module load numarray/1.3.3
