Improve project home page usability
I looked at project page and saw next problems with it:
* a lot of information but not separated on blocks - hard to understand
* unclear how to contribute to project
Instead of complete redesign I followed step-by-step changes.
### Step 1
First of all I separated Repository and Contribution blocks.
Contribution block should makes it easy for people to contribute. Even when we visit GitHub project page its not clear how to start. Our Contribution section should help with it. All repository stats and download button moved to Repository block.
### Step 2
Next step was to make top section less loaded. I moved clone panel to sidebar because it is very heavy element and rarely used. If you use web editor - you dont even use it. If you work via http/ssh you will copy remote only once. So my idea - it should be on home page but should not be in center of attention.

Use the configured display name in e-mails from Devise mailer
By default, it is set to "GitLab", but a user may configure the display name to something else.
See merge request !613
Improve help line for restricted domain signups
The setting may be misconstrued as only allowing access from certain domains. Add help to clarify this applies to e-mail domains.

Improve documentation of configuring external issue trackers
There was some confusion over the deprecated `:issues_tracker_id` field. Added documentation.
Closes#1514
See merge request !580
Added " How to maintain tight control over the number of active users..."

Fix Error 500 when searching Wiki pages
If a Wiki page turns up a hit in the search results, an error will occur:
```

An unhandled String containing the name of the Wiki page would be provided to the URL path generator. This MR handles that case.
