save project/analysis on 2D fits is broken

[pkienzle]

project/analysis save does not work for 2D fit pages.

The immediate issue is that self.version is not defined in fitting PageState?, giving the version number of the cansas schema for 2D data. Easy enough to avoid this error, however, the schema itself,

​http://svn.smallangles.net/svn/canSAS/1dwg/trunk/cansas1d.xsd

is not available, so the resulting file would not be valid.

Note: requires branch ticket-811 to test.

I have issued a pull request (30) for this ticket. I have not tested if this conflicts with the changes I made for #795, but that is my next step.

I have merged branches ticket-795 (#795) and ticket-827 into a single cohesive branch as well as one pull request (​https://github.com/SasView/sasview/pull/30). The original pull request for ticket-795 (​https://github.com/SasView/sasview/pull/22) is now closed, but the comments are still relevant to the work done.
