I installed minimal distros for 7.0.2 and 7.1 on Windows to compare sizes

99.5 MB 7.0.2
139 MB 7.1

7.1 has extra karafe bundles for xalan & xerces that weren't in 7.0.2
that adds 5MB

We now ship groovy that adds 5.8 MB

We now ship bouncycastle that adds 1.7 MB

system\org\fusesource\fabric has jumped from 9.5 MB to 31 MB
