Adding configuration variables for MAIL_FROM and REPLY_TO in EmailConfig (#97)

Browse Source 
The MAIL_FROM & REPLY_TO addresses default to appsmith@localhost. This should be changed in the generated docker.env file during deployment to actual values.

Most email providers will not send emails unless they originate from a valid sender ID.
