Changes

* Fix for the wrong unpacking of R20A and R20B in model CR72 full. Bug #22146: (https://gna.org/bugs/?22146) Unpacking of R2A and R2B is performed wrong for clustered "full" dispersion models. * Fix for the wrong unpacking of R20A and R20B in model B14 full. Bug #22146: (https://gna.org/bugs/?22146) Unpacking of R2A and R2B is performed wrong for clustered "full" dispersion models. * Fix for the wrong unpacking of R20A and R20B in model NS CPMG 2SITE 3D full model. Bug #22146: (https://gna.org/bugs/?22146) Unpacking of R2A and R2B is performed wrong for clustered "full" dispersion models. * Fix for the wrong unpacking of R20A and R20B in model NS CPMG 2SITE STAR full model. Bug #22146: (https://gna.org/bugs/?22146) Unpacking of R2A and R2B is performed wrong for clustered "full" dispersion models. * Bug fix for the lib.io.file_root() function for multiple file extensions. The function will now strip off all file extensions. * Fix for bug #22210 (https://gna.org/bugs/?22210), the failure of the 'LM63 3-site' dispersion model. The problem is described in the bug report - the multiplication in the tanh() function is a mistake, it must be a division. * Fix for the Library.test_library_independence verification test on MS Windows. The tearDown() method now uses the error handling test_suite.clean_up.deletion() function to remove the copied version of the relax library. * Fixed the packing out of parameter tex for global analysis in model IT99. Bug #22220 (https://gna.org/bugs/index.php?22220): Unpacking of parameters for global analysis in model IT99, is performed wrong. * Fix for bug #22257, the freezing of the GUI after using the free file format window on Mac OS X. This is reported at https://gna.org/bugs/?22257. This is a recurring problem in Mac OS X as it cannot be tested in the relax test suite. The problem is with wxPython. The modal dialogs, such as the free file format window, cannot be destroyed on Mac OS X using wx.Dialog.Destroy() - this kills wxPython and hence kills relax. The problem does not exist on any other operating system. To fix this, all wx.Dialog.Destroy() calls have been replaced with wx.Dialog.Close().
