v2.2.8

Bugfix release:

• uwsgi template somehow failed to produce a newline, causing bug #95, this should fix it
• Set REWRITE_HOST for labirinto (v0.2.4) to allow rewriting hostname with the one detected at run time, allows accessing underlying services when not resolvable
• fixed bug in previous fix for #88 #94, hopefully now fixed for good
• documentation: add hostname to recommended docker command after bootstrap #97
