update page.php to be more translation ready

Hey, on line 18 i've added the following so it can be translated properly with an mo file.
Cheers and thanks a lot for an awesome theme!
<?php printf( __( 'Posted', 'bonestheme' ) . ' <time class="updated" datetime="%1$s" pubdate>%2$s</time> ' . __('by', 'bonestheme' ) . ' <span class="author">%3$s</span>', get_the_time('Y-m-j'), get_the_time(get_option('date_format')), get_the_author_link( get_the_author_meta( 'ID' ) )); ?>
