IMPORTANT FOSDEM 2018

Some people have added information to the FOSDEM pad, which is related
to 2017, while the updated information for FOSDEM 2018 are on the wiki page:

https://wiki.documentfoundation.org/Events/2018/FOSDEM

For instance, the social dinner on Saturday will be in a different
location, and the information about other topics are outdated.

I will sync the wiki and the pad, but in the meantime please add your
name to the wiki (especially for the dinner, as qwe have a maximum
number of participants).
