Change plots to bar graphs

Since line plot does not make sense for this kind of plots, change them to bar graphs. Bar graphs are easier to read and they look cool too.

I would like to change commits per author plots to bar graphs too, but code looks too messy to modify.

UI Improvement for the project page

This MR improves the positioning of the dropdown menu on the project page.
I've added the WIP because I didn't check if this can cause any tests to break.
I'll remove it once the CI is green.

Fix "Reload with full diff" URL button in compare branch view

This button worked when viewing merge requests because the JavaScript
stripped the .html in the Ajax request. However, it left the .html suffix

Gracefully handle SMTP user input errors (e.g. incorrect email addresses) to prevent Sidekiq retries

### What does this MR do?

This MR gracefully handles SMTP input errors (e.g. incorrect or invalid e-mail addresses) to prevent these types of exceptions from causing Sidekiq to retry the task. If these specific exceptions occur, they will be logged, and the e-mail will be dropped from the queue.

### Why was this MR needed?

If you include an author that has a misspelled e-mail address, Sidekiq will keep sending e-mail to all the recipients even if they have already received the e-mail. The only way to recover is to clear the Sidekiq queue.

Note that other exceptions can still be thrown (e.g. `IOError`, `Net::SMTPAuthenticationError`, `Net::SMTPServerBusy`, `Net::SMTPUnknownError`, and `TimeoutError`). If the worker encounters these, Sidekiq should retry the task.

### What are the relevant issue numbers?

Closes https://github.com/gitlabhq/gitlabhq/issues/9560

Upgrade browser gem to 1.0.0 to avoid warning in IE11 compatibilty mode

GitLab currently displays the "outdated browser" message if users run Internet Explorer 11 in Compatibility Mode. @fnando [updated the browser gem](https://github.com/fnando/browser/pull/168) to use IE's Trident version to determine the "true" version of IE11.

Remove user OAuth tokens stored in database for Bitbucket, GitHub, and GitLab and request them each session

Remove user OAuth tokens stored in database for Bitbucket, GitHub, and GitLab
and request them each session. Pass these tokens to the project import data.

This prevents the need to encrypt these tokens and clear them in case they
expire or get revoked.

For example, if you deleted and re-created OAuth2 keys for Bitbucket, you would get
an Error 500 with no way to recover:

```
Started GET "/import/bitbucket/status" for x.x.x.x at 2015-08-07 05:24:10 +0000
Processing by Import::BitbucketController#status as HTML
Completed 500 Internal Server Error in 607ms (ActiveRecord: 2.3ms)

NameError (uninitialized constant Import::BitbucketController::Unauthorized):
  app/controllers/import/bitbucket_controller.rb:77:in `rescue in go_to_bitbucket_for_permissions'
  app/controllers/import/bitbucket_controller.rb:74:in `go_to_bitbucket_for_permissions'
  app/controllers/import/bitbucket_controller.rb:86:in `bitbucket_unauthorized'
```
