Init File Company-Mode Setup

[Ari King]

Hi,

I'm trying to configure company-mode to activate in all buffers, with 
appropriate back-ends depending on file-type. To that end, I've added the 
following to my init.el file. 

;; Enable global company mode
(require 'company)
(add-hook 'after-init-hook 'global-company-mode)
(setq company-idle-delay 0.1)
(setq company-minimum-prefix-length 1)
(setq company-backends '((company-capf company-files company-elisp 
company-inf-ruby company-anaconda company-go company-irony company-clang 
company-cmake company-css company-yasnippet) (company-dabbrev 
company-dabbrev-code)))

However, regardless of which file-type I open, company-mode does not 
automatically activate. Help in sorting this out is appreciated.

Full init.el file is here: http://pastebin.com/eyvvzUPW
