Add custom RSpec generators

These are "work in progress" generators which are intended to improve
the RSpec generated files when scaffolding resources.
Add scaffolded Post
Add Post

Fix scaffold, improve specs
Add Post#title presence requirement to allow to have an invalid factory
Add failing spec for issue #8

See https://github.com/gonzalo-bulnes/simple_token_authentication/issues/8
Add PrivatePost, regression spec for issue #8

I've scaffolded PrivatePost and set it as a copy of Post destined to
be protected by token authentication.

Add passing regression spec for issue #8 (PrivatePost is expected to be
protected by token authentication and should remain protected.)
Fix intrusive authentication requirement

Add manual test for issue #8, see ApplicationController.

Fixes #8

The gem, once installed, was automatically including before_filters
in all controllers, which ended in `authenticate_user!` being called
on all requests.
Now the these before_filters are, as expected, only included in
controllers were `acts_as_token_authentication_handler` was called.
Bump version number

Break strict semantic versionning compliance to make
installing the gem from Github easier, because
Bundler does not support dashes in version numbers.

See http://bundler.io/v1.5/gemfile.html and
http://semver.org/
Add Travis-ci

See https://travis-ci.org/gonzalo-bulnes/simple_token_authentication
