Moved config into hidden dir in user home, added check for file existence, otherwise creates it

Made a change to the path to config so it is in a . directory in user home. Saves polluting the home directory with visible folders.

Also added a check to the config and logger file so its created if it doesn't exist. Previously would throwing a FileNotFoundException:


run:
