Initial original copy of login directory from Moodle v2.6.5.
Replaced URLs that contain '/login/' with '/internallogin/' by running: for f in *.{php,html}; do sed -i 's|/login/|/internallogin/|g' $f; done
Stopped alternateloginurl and corrected url returned by get_login_url().
Merge branch 'Moodle-v2.6.5' into MOODLE_26_STABLE
