AP_Scripting: allow scripting to get mission item/s by index, and wp data, and details of wp

[davidbuzz]

… from lua

[davidbuzz]

example lua snippet that loop over all mission items and sends them all to the user as sent_text messages, just because. Warming, doing this specific example with big mission/s will cause lua to timeout or exceed limits etc.

missionsize = mission:num_commands()
gcs:send_text(0, string.format("LUA: missionsize %d", missionsize ))
for x = 1, missionsize do
gcs:send_text(0, string.format("LUA: mission-item %d", x ))
mitem = mission:get_waypoint(x)
gcs:send_text(0, string.format("LUA p1-4 %f,%f,%f,%f", mitem:param1(),mitem:param2(),mitem:param3(),mitem:param4() ))
gcs:send_text(0, string.format("LUA x,y,z %0.6f,%0.6f,%0.2f", mitem:x()/10000000.0, mitem:y()/10000000.0, mitem:z() ))
gcs:send_text(0, string.format("LUA seq,cmd,frm,cur %d,%d,%d,%d", mitem:seq(),mitem:command(),mitem:frame(),mitem:current() ))
end
