Added the deactivation and account recovery systems. The variable
EMAIL_MESSAGE was replaced with ACTIVATE_EMAIL, then RECOVERY_EMAIL was
added. The response variable was changed in all views to the correct
spelling. The validation file has a new function to validate the
regular expressions in an email string and not check the database. And
finally the function UserActivationKey in views was renamed to KeyGen
Added variable: "basetitle" to the config file which sets the title on
index, login and registration pages as well as the admin pages. I then
moved the code that connects to the SMTP server to above where the user
is created in registration. I did this because if the connection fails
then it wont continue and create a user that wont be able get an
activation link. I also adjusted some indentions to make it easier to
read on github.com
