Make it possible to disable fswatch

[EugenMayer]

Since if there is any ressource consumption, it would be the watcher ( fswatch ) under osx, make it possible to disable any file-watching. Even though this means the user has to either run

docker-sync sync

Himself whenever he wants to sync back or, and thats much more interesting, use IDE tools like file-watchers of e.g. Intellij to fire up the sync whenever you save a file ( of a specific glob ).

Its not a hard deal, just create watch_strategy as a configuration and allo

• fswatch ( default )
• none

And create documentation why this is offered and how to utilize the IDE for that. Anyone feels happy, please help writing docs in the wiki :)
