gui/dialogs/multiplayer.xml: added checkbox.
defaults.xml: default /sim/mp-carriers/auto-attach to false with
userarchive="y".
Multiplayer carrier auto-attach is implemented in
fgaddon/MPCarrier/Systems/MPCarriers.nas.
New dialogue is accesible from the File menu.
Allows enable/disable of three new features: multiplayer record, continuous
record and recovery snapshot. Also moved load/save tape from the file menu into
the new dialogue.
Also removed recently-added flight recorder items from the multiplayer dialogue.
The recovery snapshot interval is 1s second if enabled. Might be better to make
it longer, e.g. 5s, but don't know how to change checkbox value.
Change /sim/multiplay/transmit-only-generics to /sim/multiplay/transmit-filter-property-base, which can be 1 to transmit only generics, or a number greater than 1 to indicate the start index to transmit (e.g. 12000 for new emesary mp bridge properties)
Change to use the ports defined in the property tree when connecting from the dialog.
Ensure properties for ports are set to a valid (non zero, not null) value on dialog initialisation.
Add ability to change receive port from dialog firstly to see what it is and secondly to allow multiple fg sessions
- Now enabled even when no MP settings configured on command-line
- Add Server Status button to launch the MP Server status URL
- Minor layout cleanup.
