* The gui_raise() function now prints the error message to STDERR if the raise flag is not set.
* Redesign of all the file dialogs in the GUI. All file dialogs are now instances of gui.filedialog.RelaxFileDialog. This fixes many inconsistencies throughout the GUI, includes presenting an wx.FD_OPEN style file dialog when a wx.FD_SAVE style should have been shown.
* The PDB file selector of the [http://www.nmr-relax.com/manual/structure_load_pdbstructure_read_pdb.html structure.load_pdbread_pdb] GUI user function now only shows *.pdb files.
* Removed combine_models from the [http://www.nmr-relax.com/manual/structure_load_spins.html structure.load_spins] GUI user function page as that argument no longer exists.
* Improvements to the free file format GUI elements (window and element). This includes specifying fonts, button sizes, and a fix for the button sizer in the GUI element.
