an24b: animate propellers over multiplayer.

JSBSim populates the properties /fdm/jsbsim/propulsion/engine[*]/propeller-rpm,
duplicated in /engines/engine[*]/thruster/rpm. Either property may be used to
animate the propellers and various instruments. However neither of these properties
is transmitted over multiplayer by default. Instead, the mp protocol specifies
/engines/engine[*]/rpm. The solution is simply to:

- declare /engines/engine[*]/rpm as an alias for /engines/engine[*]/thruster/rpm
- use /engines/engine[*]/rpm for the propeller spin animation.

(it would be nice in the future to have propeller disks when rpm is high).

an24b: add /sim/model/fallback-model-index and max take-off weight to the fuel & payload dialog.
(with prior approval from maerchenprinz).

an24b: Tiller steering off by default; AChS: minute needle of timer added; R-836 model changes; minor model adjustments; Effect added
