Move service template and project service settings into a shared view

This MR reconciles the small differences in the error message layout between the template and project settings, and moves the partial into a shared view. This came from a mention in https://github.com/gitlabhq/gitlabhq/issues/9181 to take care of this.

Fix bug where commit data would not appear in some subdirectories

Fix issue where commit data would not show up in some subdirectories due to escaped slashes. For example:

https://gitlab.common-lisp.net/ecl/ecl/tree/develop/src/gc (now patched with fix)

The upgrade from Rails v4.1.2 to v4.1.9 (76aad9b7) caused slashes in a tree to be escaped automatically. Using a wildcard glob in the route prevents this behavior.

Add capybara-screenshot gem

This is a handy little gem that automatically saves the page and a screenshot when a Capybara test fails to `tmp/capybara/` so you can easily see why it might have failed without adding your own `save_and_open_page` directive in the code.

Also reduces the timeout for Capybara tests when not in a CI environment.
