PoA: New incantations

[GulPlum]

I recall from back when CoS came out, that someone was collecting new 
incantations from the movies not present in the books.

I note only three newcomers this time around, so here they are if anyone's 
interested:

Lumos Maxima (does that *really* need a translation?)
Arresto Momentum (ditto; BTW I wonder why they didn't simply re-use the 
established "Immobilus")
Bombarda (ditto again - although I'm tempted to describe its effects as 
"Alohomora with attitude"). :-)

Have I missed any?
