Add an API for expeditions

[Thurion]

Currently there is no API to get the waypoints of an expeditions via the API. It would be nice to get the following information:

• Start and arrival date
• Expedition announcement
• List of waypoints
• Next waypoint (would require API key)

I second that. If there was one I would build an EDMC plugin that would be able to show you your next waypoint and how far you had to go.

I wouldn't expect EDSM to provide the next waypoint I would just need to know what order the waypoints are in and would track locally

I'd also want to get the waypoint comments so that the plugin can display what to do when you reach a waypoint.

It would be similar to to the alien sites plugin

I forgot about the comments and they should be in the API as well.
I wanted to add it to my DistanceCalc plugin: Show the next waypoint and the distance to it. Tracking the progress locally is possible but EDSM already keeps track of it so why not add it to the API as well?

A list of participants would also be helpful. Ideally, also an API to pull the travel histories for participants, for jumps made within the duration of the expedition. That latter one has potential privacy issues though, for participants who have not elected to make their travel history public, unless additional options are added to toggle public access for expeditions as an override to their normal privacy settings.
