SEC-2119: Add a 'parameter' to <remember-me>

This change extends pull request https://github.com/SpringSource/spring-security/pull/26 and its subsequent changes by renaming the attribute name 'rememberme-parameter' to 'remember-me-parameter'.

The spelling including the additional hyphen in 'remember-me-parameter' is more consistent
with the default spelling of the 'remember-me' functionality.
