Update email layout

[willywos]

The emails that get sent out from the site that are generated from Devise, the authentication library are very plain. They could be updated to make them a little nicer.

Here is an example of the forgot password email:

Somethings to add to the email are:

• Include "JobbyJobJob" in the subject so users know what site it is
• Better welcome message
• Logo or Image identifying the site so users know where it is
• Expiration Information
• Who requested the reset? (IP Address? User Agent?)
• Contact Support information (which is just my email I guess)

Other emails that needed added

• Sign Up Registration Welcome Email
• When a user changes their password (which is handled in another issue)

Emails should be from: no-reply@jobbyjobjob.net
My email is: wwilimek@gmail.com
