removed template submodule
bring template back into lib/

commit 1d14563c8078898bdf5f5363a61cf9672b2c2764
change creator command to use template from lib/
no more template
fix reference to the puma config inside the template
check for .env instead of Gemfile.lock

something about how travis is configured to work with bundler, it
doesn't seem to be leaving a lock file.

this seems more flexible going forward too, as we might include
Gemfile.lock with the template
