bugfix, corrected missing funcall().
Working postrender example!
Updated README example.

If you use the inline views' `@` syntax to access template parameters, teacup doesn't magically propagate the variables for you, so use fat arrows!
layout has been gone since partials have been gone..
Added @session (aka express-session) in main scope, refactored the share_* examples.

Note: the examples are not working yet, I haven't updated the zappajs code to account for changes in Socket.IO 1.x wrt store vs adapter.
(I'm not even sure whether the `adapter` code does what the former `store` code used to do...)
