mail from email and name depending on Laravel environment variables

[xaviqv]

I've found out two files where the mail from address is directly typed instead of using Laravel environment variables. I guess this is an error so I propose this change.

Anyway, thanks for your great project! Actually this is my first contribution but I hope it won't be the last!

@xaviqv Its a nice contribution.
Doing this will also have to update the .env file.
Please write code to installation for adding two new lines:

MAIL_FROM_NAME= LaraAdmin
MAIL_FROM_ADDRESS= [email protected]

Please add these changes and update your pull request. Will accept it.
Best Regards,
