astro/xearth: Add myself (lbartoletti) to astro/xearth/files/freebsd.committers.markers

[lbartoletti]

Summary

Add myself
And fix ashish, flo, ade, ler, kbowling, dhw

Test Plan

Opened with xearth.
BTW I wrote a script to export our markers file to GeoJSON so we could open it in graphics/qgis (for example ;) ) or use it to produce a map on the web like OpenBSD developpers does.

Here is the preview of this kind of map: http://umap.openstreetmap.fr/fr/map/freebsd-committers_483423#3/20.80/12.48

maybe you can add the script to xearth too?

(you could split the commit into two parts 'fixing syntax' and 'adding myself')
