Fix typo in the guide introduction
Fix cowboy_websocket_handler callback spec
Replace terminate/2 with terminate/3, adding a Reason

This should have been done a *long* time ago, back when I initially
added Websocket support. This is the first part of two in improving
loop handler support with regards to socket closure.

Reason may include: {normal, shutdown} for the most normal shutdown,
{normal, timeout} for a loop handler timeout shutdown, or {error, _}
if an error occured.
Do not require inets for running tests anymore
Make cowboy_static use universal time
Merge branch 'master' of https://github.com/0x00F6/cowboy
Do not crash if connection is closed while sending static file
Fix handler state change in cowboy_rest
Add HTML5 Video Example to the static example
Merge branch 'fix_change_state' of https://github.com/nevar/cowboy
Remove cowboy_dispatcher

Types and code are moved to cowboy_router. The match/3 export
from cowboy_dispatcher isn't available anymore as it is called
internally.
Update handler callback specs

There is one another {upgrade, ...} quintuple allowed as the result of
Handler:init call, somewhy not mentioned in the callback specifications.
New routing

Ultimately few things change, it's mostly just a nicer syntax and
slightly different expectations. The name of the value `dispatch`
did not change, because the previous dispatch values will now fail
if the code is not updated to using `cowboy_router:compile/1`.

No constraints have been implemented in this commit.
Add the 'int' constraint
Add the 'function' constraint
If a binding is reused, we check that values are identical

This is more for consistency than anything.
