Make options arguments truely optional

Currently the options help, info and debug must exist in the options
dictionary; however it might be that this is not the case if a method is
imported externally. This patch fixes this.

Also support using a storage URL or path as an argument for tempurl, and
adding a test to verify correct output in both cases.
