v1.7

Changes since v1.6:

• Rework handling of ACME account keys ( 7f66758 #312 )
• Change REUSE_KEY to REUSE_PRIVATE_KEYS to avoid confusion with account keys ( 63403f7 )
• Remove the --only exposed argument to docker-gen ( #230 #281 )
• Update the base image to Alpine 3.7 ( d27d4cf )
• Set the image exit code to 0 ( 6c6f131 )
• Make LETSENCRYPT_EMAIL optional ( 1bb6e86 )

Bug fixed:

• Fix issues with trimming on the go template and with rm -rf on paths that might include an empty var. Both issues could send the container in an endless loop ( #289 fix for issues #254 and #288 )

Other changes:

• Addition of a basic Travis CI test suite ( #285 )
• Updates to the documentation ( #257 #292 #297 3c35d72 )
