Stability & Security updates

[danielpclark]

This is similar to PR #79 .

UPDATES:

• Ruby updated to 2.3.4
• Rails updated to 4.2.8
• ActiveAdmin updated to 1.0.0 stable
• And other stable updates

---

Security updates for Rails includes previously mentioned:

• CVE-2016-6317 5/10 Threat
  Action Record in Ruby on Rails 4.2.x before 4.2.7.1 does
  not properly consider differences in parameter handling
  between the Active Record component and the JSON
  implementation, which allows remote attackers to bypass
  intended database-query restrictions and perform NULL
  checks or trigger missing WHERE clauses via a crafted
  request, as demonstrated by certain "[nil]" values, a
  related issue to CVE-2012-2660, CVE-2012-2694, and
  CVE-2013-0155.

• CVE-2016-6316 4.3/10 Threat
  Cross-site scripting (XSS) vulnerability in Action View
  in Ruby on Rails 3.x before 3.2.22.3, 4.x before 4.2.7.1,
  and 5.x before 5.0.0.1 might allow remote attackers to
  inject arbitrary web script or HTML via text declared as
  "HTML safe" and used as attribute values in tag handlers.

Server was complaining about backbone-min.map and
underscore-min.map missing so I added those in.

ActiveAdmin pages when first visited from the main site
would falsely include the application template. A
Javascript fix was implemented for this.

ActiveAdmin logout would previously exit to the admin
login page. This has been fixed.

Navbar had a drop down menu with no useful links. This
has been removed.

A few links were painfully huge at header 1 size. I've
reduced those to header 3 size.

If you find these changes acceptable I would really appreciate having them merged in.

@h-m-m Should I ask some one else to review?

For any changes, please create a feature branch and open a PR for it when you feel it's ready to merge. Even if there's no real disagreement about a PR, at least one other person on the team needs to look over a PR before merging. The purpose of this review requirement is to ensure shared knowledge of the app and its changes and to take advantage of the benefits of working together changes without any single person being a bottleneck to making progress.

I'd feel best if someone on the project looked since I don't have much context. That said, I don't see anything glaring there. Pretty straightforward changes that don't involve any business logic of sorts. 👍 Thanks for putting in the work!
