Assorted termination simulation cleanup.

- term/Makefile: "make qucs" shortcut for invoking qucs
- term/term.sch: disable switch to .dpl page after simulation
- term/term.sch: changed R3 from 50 Ohm to the more common 47 Ohm
- term/term.sch: changed C2 from 22 pF to 330 pF to match TVS
- term/term.sch: renamed Vin to Vdst and put graph in diagram on top
- term/term.sch: added more annotations
