Update ui_guide.md with button capitalize rule

cc @jschatz1 @hazelyang @skyruler 

See merge request !5161

Update New Snippet buttons.

## What does this MR do?

No longer shows New Snippet button to users who aren't able to create a new snippet in the given context.

Also removes the plus icon from the New Snippet buttons, as they're no longer used in other creation buttons.

## Are there points in the code the reviewer needs to double check?

Make sure the snippets pages don't break or show the buttons to users who shouldn't have access to them.

## Why was this MR needed?

Users that weren't logged in would click the New Snippet button and get a 404 error. You would also get 404 errors from the New Snippet button on project snippets for projects you weren't able to create snippets for.

## What are the relevant issue numbers?

Fixes #14595.

Fix gemfile

1. replace `"` to `'` in Gemfile.

2. change `require: nil` to `require: false`.
`require: nil` and `require: false` get same result, but i think we shouldn't write it differently in other places.

3. set version for gems.
better gem's version control for prevent dependency errors.

Avoid calculation of closes_issues.

## What does this MR do?

Avoid unneeded calls to MR closes issues

## Are there points in the code the reviewer needs to double check?

I'm not sure if calling this method from a view is a good practice, but I cannot see another simple way of avoiding this problem. In case we want to avoid this in the controller we need to specify the action, format and status of the merge request, because in that case we know that the `_open` partial will render. We could add some lazy evaluation but it not a thing I see in use along the app but feedback is welcome

Fix documentation for Github integration authorization callback url.

There are two callbacks that could be used with Github integration:

  * /import/github/callback (used by project import)
  * /users/auth/github/callback (used by OmniAuth)

Github's documentation suggests that authorization callback url should be
set to the longest common path.

https://developer.github.com/v3/oauth/#redirect-urls

Configuring according to the previous documentation resulted in a
redirect_uri_mismatch error from Github when logging in via OmniAuth.

Fix: Infinity Bug in Commit Statistics

## What does this MR do?

It fixes a logic bug in the commits statistics: The code assumed that the amount of days involved in a commit range is equal to the difference between the first and last date. This is not true, though, as (from a human standpoint), a commit yesterday and a commit today involve two days, not one. Similarly, a fresh project with only commits made today already 'used' one day.

Since the number of involved days used to be zero for new projects, the result for commits per day quite often amounted to `Infinity`…

## Are there points in the code the reviewer needs to double check?

The test file. I hope it is up to the standards of GitLab.

## Why was this MR needed?

The bug occurres especially for new users with their first project while exploring GitLab.

## What are the relevant issue numbers?

This bug was reported as #1548.

## Screenshots (if relevant)

Added setting to set new users by default as external

## What does this MR do?
This implements the feature request #14508. It adds an option in the application settings to set new users by default as external.

## Are there points in the code the reviewer needs to double check?
Everything. Like I mentioned in the discussion of the issue my knowledge of Ruby basically doesn't exists. I tested it on my machine and it seems to work, but as I am very unexperienced in Ruby I highly recommend to  take a close look at the code.

## Why was this MR needed?
It was requested by @DouweM to work on the issue with the proposed changes by me.

## What are the relevant issue numbers?
This MR is for the issue #14508 that followed up after the implementation of #4009.
