Change the check level of scalastyle from warning to error.

To check style errors on Travis, the check level must be changed to error.
Otherwise "sbt scalastyle" command exits with 0 instead of nonzero exit code.
Check style errors before running tests on Travis.

Run tests only if there is no style errors.

Return 404 Not Found status code without body when a handler is not found.

The default onHandlerNotFound method returns an error page in HTML. This is
unnecesary because the clients of Beyond framework check only the status code.
Changed to return only the status code if a handler is not found. This change
is in effect only in production mode.
Add login and logout actions.

Add session management actions: login and logout. login stores the username in
the session so that subsequent authenticated actions can access the username
from request parameter. Here, Authenticated is used as a helper object to
create an authenticated action.

Currently, password checking in login is not yet implemented.
