first working prototype of sbt-statika that use sbt-s3-resolver v0.4.0

I suggest to migrate ASAP to new resolver because I just coun't compile generated bundle (see https://github.com/ohnosequences/statika/issues/43).

So I tried to change sbt-statika to make it work with new resolver and it seams that it works (at least now I can compile generated bundles).

remove ugly paths to my keys
