Sharing should have a way to not share some environments

[Alfred Nutile]

User should be able to share but remove @prod for example

php artisan envdeployer:share --not-including=@prod

This would allow it to be easier to share depending on the level of access that developer has

So by default when you do 'push' only the values are pushed to the environment. But share would send over an exact copy of your .env

The user would do

php artisan envdeployer:share get 

to get it and at the moment it will cause a deletion of the file
