initial gemspec, standard lib files
fix requires - in engine, using loadpath or using CORE_ROOT
more dependency fixes for the engine
move more dependencies from Gemfile to the gemspec
THEME_ROOT e.a. are relative to CORE_ROOT not Rails.root
bring back castle_gates and use permissions relative to CORE_ROOT
add locales/en to the locales path for the engine
Clearify ::Page so there is no confusion with Crabgrass::Page

This caused travis build to fail before.
do not depend on active support in crabrass/info

it's loaded very early - even before AS
updated Gemfile.lock

I guess this is due to dependencies moved into gemspec from Gemfile
do not require the engine by default

If we run Crabgrass::Application directly we don't want to load the engine as it duplicates everything.
Had to move the require statements out of the engine file into new crabgrass/dependencies.
load crabgrass/boot from crabgrass_core directly
