Updated to work with Evernote OAuth

Used patches from
https://github.com/kechako/emacs-evernote-mode-developer-token and the
latest enclient.rb patches from the Google Code bug at
http://code.google.com/p/emacs-evernote-mode/issues/detail?id=14

This seems to be working for me so far.  Still testing.  I'm new to
Evernote.
Removed authentication refreshing

Since all authentication is done with OAuth in the ruby client now, we
probably don't need to refresh authentication.  It's just causing
errors anyhow.
Adding defcustom and defgroup for easier customization.
Create README.md
Adding some instructions and background in the Readme.md.
Fixing markdown.
Merge pull request #1 from ayman/master

defcustom/defgroup addition
Added a .gitignore file

This should help.
Updated .gitignore
Added org-evernote interface

You can now org-evernote-pull
This still needs some work, but it's a good start and it's working
pretty well.
Make sure org-evernote-pull is logged in

This should make sure that pulling notes from Evernote happens in a
logged in state.  This hasn't been tested much.
Use Evernote's official API

If we want to keep up with the latest versions of things, we don't
need our own version of the Evernote Ruby API.  It's available in
gems.
Fetch and serialize note attributes

The note attributes contain a lot of good metadata, such as reminder
times and last updates and that sort of thing.  This is definitely
needed for a good org-mode interface.
Make this act like a library

The org-evernote file now provides 'org-evernote.
Seemed appropriate and like a stupid oversight.
Remove unneeded and incorrect defun

Oops, I committed broken code. This should work quite a bit better. At
least it eval's properly.
Should solve issue #7 in /rubbish/evernote-mode
Should solve issue #7 in /pymander/evernote-mode
Improved the previous commit so that we can use a comma as separator.
