Whole analysis .Rdata export should be able to save multiple analyses

[julianstanley]

On the "Analysis" tab, users can save a bunch of different graphs/analyses.

However, when they export their data to RData on the "Sharing" tab, only the current analysis is saved.

Really, that big RData export should include all of the analyses that they saved. This should be straightforward to implement, it just means that I need to also pass save data from mod_home to mod_analysis.
