#1 Save/Load .csv files

[gradberg]

Add the ability to save and load .csv files. It should be easy, and I bet it can just keep any extra space-formatting, and just simply throw
commas in-between each cell.

The real question is, is there any way user-entered commas can be present in the .csv file? Are they escaped in any way, or will a check have to be made to warn the user if they've entered commas that they'll be removed.
