updated README
Merge pull request #7 from rdsoze/master

Edit Readme
Make sure gemset is created
Merge branch 'master' of github.com:skorks/omniauth-linkedin
Adds ability to specify permission scopes

Upades the strategy to allow scope specification. Updates
readme and example app. Ups the version, make sure
we use the latest omniauth gem.
Make scope list space separated

Having the scope parameter as a plus separated string caused
linkedin to throw invalid scope errors. Making it a space
separated string seems to fix that. Also rejigging how we
actually add the scope when we fetch the request token
to be more inline with what omniauth provides i.e.
adding scope to the request_params hash.
Now conformant with omniauth schema

The info hash should have all the fields as per the omniauth schema.
Nothing is removed so it is backwards compatible. Location should
be populated sensibly. The example now hardcodes the key and
secret. Ups the version for release.
