SANS GUI: Add options to the Save dialog

[Martyn Gigg]

The Save button on the SANS GUI is a bit basic and needs options (check boxes) for CSV, RKH and CanSAS1D. The reduced workspace should then be saved in all of the requested formats.

Time estimate: 3.5 days including testing and updating documentation

Getting the SANS form layout correct and creating the dialog box GUI will take half a day each. Coding the default save will be one and the custom save one day. Allow another day for testing. Estimate 4 days

(In [5326]) FileProperty objects now can have a default extension, accessible with getDefaultExt(). The default extension is the first extension that was passed to the FileProperty's constructor. re #1263

[Steve Williams]

(In [5330]) There is a new dialog that allows saving multiple workspaces in multiple formats. It's accessible from the SANS GUI under "Save Other". Other controls have been added to the SANS GUI to aid loading files and the interface has been rearranged a little. re #1263

(In [5334]) Attempt to fix the Mantidplot failure on Darwin by simplifying the code in the region of the error re #1263

Total time spent completing this was about 4.5 days
