[Vala] New Vala Language Server

[bernhard guillon begu org]

Hi,
because there was a recent discussion about to implement another Vala Language Server. I just wanted to 
inform you that there is a new one [1] which looks really good and active. There is also a gedit plugin to 
test it [2] :). It is unfortunately not listed at the wiki. In my opinion it is more advanced then the other 
ones.

Regards,
Bernhard
