~ in local weblog path should be converted to full path
Brought to you by:

If you use ~ as shorthand for the home directory in the local weblog
path, it will be accepted and usable for storing files, etc., but when Blapp
tries to create an NSDirectoryEnumerator to load all the posts from disk,
it fails.
Probably what should happen is in the controlTextDidChange method,
check if the local web path contains a ~, and substitute the actual home
directory path for it.
