[LGM] archiving the 3015 and 2016 websites

[ale rimoldi]

hi

today, we have run out of space on the lgm server...

i already had a 2015 static site almost ready, and i have now replace
the wordpress version with an html-only one.

https://libregraphicsmeeting.org/2015

i had to delete the original wp version to be able to continue the work.

the next to be made static is 2016:

https://libregraphicsmeeting.org/2016

the wordpress version is still on the server but due to its size i
cannot really download it.

can anybody check if everything is correct?

ciao
