allow novoda's plugin to auto gpg signing on bintray

[marandaneto]

bintray's plugin already enable us to do that, but novoda's plugin not yet, we basically can achieve that adding a single attribute called sign, I've have set the default as false, so no side-effects nor breaking changes.
sign being true will tell bintray to sign artifacts using your custom gpg keypair if you have set one or bintray's keypair if you have chosen to use theirs, this is an opt-in feature.

I've made a PR for that, but it's only to show how simply would be, no tests yet (by tests I mean unit-tests).

I already have tested it and it works with this single change.

would it be possible to have an update here? at least if you all aim to have it as a feature, thanks.

PR merged, new snapshot with this change is released: https://bintray.com/novoda-oss/snapshots/bintray-release/develop-38

I'm preparing the release for 0.9.2 in the meantime

[mr-archano]

The PR is ready to go, I am waiting for an admin to take care of it (I am not part of the Novoda GitHub org anymore, sorry). That should be enough to release 0.9.2 in Bintray for everyone to use.

@mr-archano sounds awesome, thanks a lot, looking forward to using it :)

[mr-archano]

@marandaneto you could start using the snapshot if you like https://github.com/novoda/bintray-release/blob/master/README.md#snapshots
In the meantime I will ensure we can get a release as soon as possible.
