Bump version to 1.4.5 to release #518

[mattboldt]

• I noticed 1-4-stable contains the feature added in Add extract_access_token option to OAuth2::Client #518, but it's not released in v1.4.4 right now. So here's a PR to bump it.
• I also noticed a different fix, from [Microsoft] fix reading OpenID Connect token responses #243, is in master, which is supposed to include v2 features? Shouldn't Add extract_access_token option to OAuth2::Client #518 override this?
• Updated README since bin/setup and bin/console were deleted.

Thanks @mattboldt !

@mattboldt the answer to your question is:

Yes, #518 must be ported to master, and hasn't been thus far. There was an attempt at a older, but similar solution merged to master (#516), but it was later reverted.

ref: #516 (comment)

This is one of the reasons why we still do not have a v2 of the gem ready.

@mattboldt 1.4.5 is released

[mattboldt]

@pboling Thank you so much! Do y'all plan to merge 1-4-stable -> master for v2, or will you be cherry picking certain changes? I could look into getting #518 ported to master. I think the default proc should support what v1.4.5 does now.

Edit: fwiw, before I discovered this fix, I started on a PR to improve exception handling around missing tokens. It's kinda moot now, but I think the idea has merit https://github.com/oauth-xx/oauth2/compare/master...mattboldt:add_error_message_for_missing_tokens?expand=1

@mattboldt There will be no merges from 1-4-stable to master. Generally fixes will not be back-ported unless someone wants to do the work. Maintenance effort will go into preparing 2.0 for release.

I do occasionally cherry pick things, but the branches have diverged in many ways.

I will take a look at the branch!
