Add POIs in the exported route

[bagage]

I thought that there was already an issue about that, but I'd like to:

• draw points on BRouter website, and enter a name for each
• then, when exporting the route (at least as GPX), export these points as waypoints.

GPX syntax is:

<gpx>
  <wpt lon="3.866962" lat="43.674468">
    <name>My POI to visit</name>
  </wpt>
 <trk>...</trk>
</gpx>

NVM, it was on brouter engine side: abrensch/brouter#91

I can see that you @Phyks already started working on it. Have you a plan for brouter-web side?

[Phyks]

I started to work on the BRouter side, adding an exportWaypoints parameter to export them in the traces (any file format). This is currently a boolean exporting all (from, to, via) or nothing.

This is replicated in brouter-web in #221, but still very basic.

Indeed we talked about it and indeed currently we can export brouter
markers as waypoints (from, to and via).

I'll add a button in brouter-web to add another type of waypoints, which are "not on the route" markers (nearby restaurants, campings, etc.), where one can add some custom text. Is that ok for you @nrenner @Phyks?

Ok for me (although encoding user input is not properly solved yet, will create an issue with a suggestion). Would be useful for all formats.
