Add terminal-notifier in order to notify when synced

[midN]

I don't know if you want to merge it or is it any useful for anybody else.

For me personally i found the need to get notified whenever files were synced so i know i can safely refresh page during development now.
So that's why terminal-notifier was added.

It can be made optional if there are some objections though

[EugenMayer]

could you explain, what happens, when the notifier is executed? I am absolutely interested in this feature, but could we have it, for now, as an opt int, so creating a sync-option for "notify" and then only do this, when this option is enabled?

[EugenMayer]

Ups, forgot something: Thank you for the contribution!

@EugenMayer - When the notifier is executed, it sends a simple Mac/Apple notification, which looks like this ( Right Top Corner):

Agreed, sync-option sounds correct way to go, i will add it and update PR

[EugenMayer]

eventhough i like the idea, it could actually get a bit noisy, so lets make the option and go with it, great idea having those notifciations

[midN]

@EugenMayer - Added it as an config Option, was going to make it as command-line variable, but since they are not Globally defined anywhere it seemed too extreme, so went for option thingy. I added it to example/docker-sync.yml as well

remove this please

[EugenMayer]

that looks great already, please just adjust the changes / names and we are good too merge

[midN]

@EugenMayer - Adjusted names and removed VERSION change

[EugenMayer]

why do we need this?

[midN]

It's great to have ctags incase somebody uses them for development, in my case i use it in combination with vim + autocomplete to jump between methods efficiently and autocomplete

[EugenMayer]

i see, why not

[EugenMayer]

great contribution @midN thank you a lot!
