Ability to save or export visualization properties and import them into other analysis

Users with complex visualizations (with a large number of properties/configurations) require the ability to export just the visualization metadata such that they can be imported into other analysis for use with similar data sets.

At present, to save all the visualizations designed by a user, they must save a copy of the whole analysis as a .dxp. If they need one graph from this analysis in another analysis, they will have to recreate the analysis from scratch.

Another scenario is where multiple users maintain their own copies of an analysis and one graph needs to be re-used between all the users on tables with the same structure but different data. If this utility exists, the visualization will only have to be created once and can be exported with access given to specific users for re-use.

This feature can be supported with a right click option 'Export >> Visualization to File' on all visualizations.
