Added a data dire for Mealie (#52)

* Added a data dir for Mealie

When you restart Mealie, any changes you make are reset, this is because it had no data directory bind.

Simply added a new data directory bind config option to solve this issue

* config should just live tbh, no need for all this extra other stuff.
Volume > Bind

* we dont need no if statements

* ew white spaces
