bugfix neverExpires leaked threads
mkYesod avoids using reify when it isn't necessary. This avoids needing to define the site type below the call to mkYesod.
- Add CSRF protection functions and middleware based on HTTP cookies and headers #1017
- Add mkYesodWith, which allows creating sites with polymorphic type parameters #1055
- Do not define the site type below a call to mkYesod (or any variant), as it will be required at splicing time for reification. This was allowed before because reification was not in use. Reification was introduced to allow parametrized types to be used by mkYesod (and variants), with potentially polymorphic variables.
