filenames with spaces lead to error: source and destination are required

[schlichtanders]

Every time kubycat tries to syncronize a single file called saving and loading.jl it fails with

- error:
 ---------------------------------------
 - error: source and destination are required
 ---------------------------------------
 - exiting with code 1...

I guess it is because of whitespace issues.

It would be really awesome if this Bug could be fixed. I am running multiple times a day into it.
