+syndic.1.1

@dinosaure You must generate the tarball with `make tar` and add it to the release (I have done it, [here is the tarball](https://github.com/Cumulus/Syndic/releases/download/v1.1/syndic-1.1.tar.gz)).  The current tarball is what Github generates automatically from the repo where dynamic mode is used — thus requiring oasis.
→ update the tarball [location](https://github.com/Cumulus/Syndic/releases/download/v1.1/syndic-1.1.tar.gz) and md5sum and remove the oasis dep.
