Reworking of the "Messages" interface in the patron display for manipulating standing penalties.  Not yet complete, but functional.

TODO:
Need to add a field for staff initials if a specific OU setting is present, and need to add a section and some methods for "archived" messages.  Also need to change how penalties are expressed in the summary sidebar.  Also need thought on
how/whether/when this will replace the existing Notes infrastructure, since it can do the same thing but better.

NOTES:
Experimenting with xul toolbar/toolbox; there's a beep when you use the hot key for the Actions menu that this might be the cause of.  Also, we're actually using the Dojo openils.PermaCrud code for
modifying existing penalties.  Exciting :)
