Remove require 'rubygems', gem calls (they make the gem unusable outside of rubygems - rubygems should be in RUBY_OPT)

added '-R' option to require additional files
ignore unknown macros ('acts_as_whatever') (with specs!)

fix the dependencies so it doesn't fail when multiple version of Rails is installed, reported by kuroda

tagging 2.2.2

* update gem with newgem
Add my plugin addons:
* annotate geometrical columns
* annotate object daddy
* annotate spec models
Annotates in the end by default.
