Rename before uploading

[thomasmcneill]

I'd like to see if we can add an option when saving a file to have the file on the server renamed with an added timestamp exenstion rather than being overwritten. This gives a previous version ability but I did see some people say their files were lost upon saving when a connection was broken. This prevents the original from being lost.

I did see the project uses CodeBlocks and I did see a rename function in the FTP wrapper so I might just jump on it myself if I find the time.
