Serials planning updates patch 1/3

This patch addresses usability and interface bugs in the javascript irregularity checks by
adding extra controls: 'test pattern' button (always visible) replaces the 'irregularity' link
that was previously only sometimes visible.  A 'show advanced pattern' button will display/hide the
base prediction table at any time.  A 'reset pattern' button is added.  The form may now also be submitted
even if it fails the irregularity test, as there are cases when this will result in the desired behavior.
