Dynamic form validation

[Erica-Fer]

The registration form cannot validate input as would be expected. It currently will only be able to check if passwords are the same by pressing the "submit" button, which is clunkier than just flagging it real-time, like it flags an e-mail which does not have an @ in it. Desired validation behavior which should occur without submitting:

• flag if your password is not the right length
• flag if you passwords do not match without submitting
• flag if you have not put in proper special characters
• flag if you do not have a combo of upper & lowercase characters
• flag if your email is not in the following form: @.<com/edu/etc.>
• flag if your email already exists (cant create duplicate accounts)
