Fix issue #16 reported by @crazykt

Previously when Boogie was passed the ``-proc:<NAME>`` argument on the command
line it would verify any procedure whose name contained ``<NAME>`` which
doesn't seem like correct behaviour.

Now Boogie only tries to verify a procedure only if its name matches
``<NAME>`` exactly. I've added several test cases to check Boogie
behaves as expected.
