relax SVN archive

Disabled the 2 generic peak list system tests.

This will prevent users complaining of bugs in relax, when this is simply testing as-of-yet uncoded
methods.

Ported the CHANGES file for relax version 1.2.15 to the 1.3 line.

This was obviously forgotten when the release was made.

The command used was:
svn merge -r8033:8034 svn+ssh://bugman@.../svn/relax/tags/1.2.15 .

relax version 1.3.4.

This release includes numerous new features and bug fixes.

Massive clean up of the float module unit tests.

As a general clean up, the module has been converted to the relax coding conventions. Importantly
the floating point numbers defined as constants for the tests are now properly defined using the
packBytesAsPyFloat() function. This will allow these tests to pass on all machines!

Caught a NaN problem in __q_factors_rdc() causing a system test to fail in Windows.

Redid r9279! This was accidentally reverted by hand in r9282!!!

Removed a reference to the '..' dir.

Removed the last '/' directory separators to be more non-Unix operating system compatible.

Modified the shared data scripts to be more non-Unix operating system compatible.

Modified the system tests to be more non-Unix operating system compatible.
