Typo fix
Updated generated files
Make the tests depend on their config files, too
Run the tests in a way that handles filenames with spaces
Modularized running rsnapshot and executing a command to get the return value
Used new functions
Made several tests actually use the command result instead of the output
Removed some debug code
Added a TODO file for testing
First round of new tests
Added some tests, some of them fail
Don't allow a logfile which exists but is not writable
Tested the remaining options for file modes
