Support deleting instruments

[GoogleCodeExporter]

In the instrument view, would like to support deleting an instrument along
with all of its data.  Should prompt for confirmation before deletion.

This will also affect any strategies which may reference this instrument.

May be worth looking into adding referential integrity back into MySQL.

I checked in some changes to Instrument.xml, PlatformDAO.java and 
InstrumentView.java
which support deletion.  However, the views don't fully synchronize, especially 
into
the Strategy view.  Not sure what the best way to handle this would be.

Damiaan, your idea of directly invoking refresh() on the other views does 
technically
work, but it violates the notion of separation of responsibilities.  I wonder 
if we
can use an event-based notification which would work better.  That way, each 
view can
listen to events and update itself as necessary.
