[OSGi] Multibindings and AssistedInject JARs need version property for fragment host #1049

The libraries "guice-multibindings" and "guice-assistedinject" are implemented as OSGi fragements for the "com.google.inject" bundle.
If two versions (e.g. 3.0.0 and 4.0.0) of Guice are used within the same OSGi container (Eclipse Equinox) then the following exception occurs:

java.lang.LinkageError: loader constraint violation: loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) previously initiated loading for a different type with name "com/google/inject/Binder"

I think this is due to the following line within the MANIFEST.MF of each bundle:

Fragment-Host: com.google.inject

The Fragment-Host should not only specify the host bundle but also its version:

Fragment-Host: com.google.inject;bundle-version=4.0.0
