Updated rubies in travis build

Removed 1.9.2 as no longer supported
Added in 2.0.0. Need to add 2.1.1 as well but will do that once the gem
is up and running on 2.0.0.
Removed odd module declaration

There was a strange declaration of all the modules contained in the
inital boot file. In order to remove this, it was necessary to rejig
some of the other dependencies.
