Skip minor version in ServiceMix and NMR release

In preparation for releasing the next ServiceMix 4, Chris proposes
that we skip a minor version number and release as NMR 1.2 and ServiceMix
4.2. There are a couple of reasons for this. First, we have a few of our
own bundles in both NMR and the Features projects that will actually be
numbered the same as the release. As we know, this can cause problems for
some people using SNAPSHOTs because the SNAPSHOT version will actually be
considered as newer than the release due to OSGi versioning semantics.
Second, this is going to be made worse by some of the open source users
that are mixing in parts from the FUSE distribution which is already at 4.1.
