Synclosure is not creating folders specified with cmdline destination option
Currently it is checking if it exists, and if not, doesn't create it.
Fixed #48: Synclosure will now accept a destination via command-line and create the folder if it doesn't exist. In addition, the previous hard coded behavior of creating subdirectories based on the feed title has been modified to use a boolean flag: usesubfolders
If the destination isn't set, the default behavior is to use the current directory for downloads. There are a few issues with the sources.ini and cache.ini files being recreated instead of using the copy in the same dir as the script, but that will be fixed on #52.
