make the 2015 site static

[aoloe]

Todo:

• [ ] send an email to ginger and ask for a final post to be put on the home page in place of the news feed
• [ ] add the links to the captions in the program page

i have replaced the 2015 site with a static version done with

• wget -r -np http://libreagraphicsmeeting.org/2015/
• renaming wp-content/themes/lgm15/style.css\?ver\=4.3 to [...]/style.css

• creating an .htaccess file with the content

  RewriteEngine on
  RewriteCond %{THE_REQUEST} \ /(.+)\.php
  RewriteRule ^ /%1.html [L,R=301]

• remove the version from all the files with a ? in the name (found with find -L)

the old site is still there as 2015c/ but i plan to remove it soon and reuse its database for the 2016/ site (after having emptied it)

anybody sees a problem with it? anything that fails after moving to the static site?
