Offline Central installation misses some JBT bundles

Removed items include:

org.jboss.tools.vpe.cordovasim.feature (and source)
org.jboss.tools.maven.jbosspackaging.feature (and source)
org.jboss.tools.common.mylyn.feature (and source)

Problem w/ removing these is that the JBDS Central plugin.xml requirs all three of them in these connectors:

JBoss Hybrid Mobile Tools + CordovaSim
JBoss Tools Maven Packaging Configurator
Mylyn support for reporting JBoss JIRAs and Red Hat Bugzillas

So if we remove them, then those connectors can't be installed in JBDS.

Possible workarounds:

a) do nothing and accept that for offline installs, you need the update site (not the installer) + central zip; also accept that the installer != update site

b) put these 3 features in the installer so that the installer contents == the update site contents (except for sources) [I did this in JBDS-3071 but nivologd@gmail.com reverted it]

c) move these 3 features into the JBDS TP; this is bad because it creates an ugly dependency chain: JBDS -> JBDS TP -> JBT -> JBT TP... every time JBT rebuilds, we need to update the version of org.jboss.tools.* in the JBDS TP

d) move these 3 features into the Central TP; this is bad in that as in (c) we would have to keep updating the Central TP each time there's a new JBT release... but we already have this problem because of Arquillian being included in the EA TP.

Since (b) was rejected, clearly the solution is (d). Or do nothing and annoy offline users with (a).
