v1.17.0.0

WARNING: This release breaks backward compatibility, previously we used /usr/bin as default skaware binaries folder, now everything is deployed in /bin which would break everything that doesn't point to that folder. Probably, if you didn't use absolute paths for skaware (execline, s6 or s6-portable-utils) you don't need to care about this change because everything will continue working (largely because we have kept execlineb in its place, /usr/bin/execlineb which is a symlink to /bin/execlineb). The change is motivated because there could be collisions with other applications. See #72 and #111.
