CLI help and version flags

Introduces CLI --help and --version commands.

NOTE: This version changes the way that NotePack responds when running notepack without arguments. Instead of showing all open todos, it prints an error and shows help instead.

User folder watcher

Moves the "watching" file into the user's home folder instead of local to the installed package. This will allow upgrades to the package to know if a watcher was running previously and restart it with the updated scripts.

Note: it is recommended that you run notepack stop before installing this release or the old process will continue to run in the background.
