Inconsistency in platforms vs tools release in cordova-coho docs

The procedure for tools release is that once the tools release is made, version must be incremented to new -dev version. This does not seem to be the case for platforms release.

I think we did not catch this for a long time since the coho tools automatically marks new "-dev" version in master, in case of release from master. But in case of release from non-master branch this does not seem to be the case.

This should be relatively straightforward except for another factor: in case a proposed release does not pass the vote the procedure is different: for tools it says we should go on with the next release while for platforms it says we should do a revert to go back to the previous "-dev" before fixing. I think this inconsistency should also be resolved, somehow.

As a workaround I would mark the "-dev" version in a patch branch before committing any changes to a non-master branch, for example: https://github.com/apache/cordova-android/pull/470

P.S. I think it would be best to get agreement via dev@cordova.apache.org, cannot tell for sure when I will get a chance to do this.
