#2 Save/Load .xlsx files

[gradberg]

Its definitely feasible to support some level of native .xlsx opening and/or saving. Obviously the full feature set is not supportable, but it might be advantagous to be able to do this.

It would be alot of work, because I doubt I'd want to deal with integrating with Microsoft's Office Open SDK platform. Relying on that would make this heavier than a lightweight, standalone application.
