Moves menu generation after component runs

Moved the commit button to the top of the list in a tfoot tag so that it appears even when there are errors

More work really needs doing to ensure titles going into the database are encoded correctly.

update milliways component to version found on live site, adding tags support(?) and sanitizing mwuri page titles before display

add a new function to save a message flash in the session data to be displayed on the next page load (e.g. when we're doing post/redirect/get)
