this curly bracket got lost, somehow

We show in small font size the same info that is shown on sign_in page:

    "GitLab Nexedi Edition", "About GitLab" and "About Nexedi"

This is good to have and hereby-introduced about-footer area will be
also used in the next patch for ICP too.

XXX placement of .about-footer to be near bottom is done not very
correctly.

Like Omnibus, SlapOS version does not have init script - nothing to
check here.

Use component.color(:<color name>) instead of component.<color name>

This is handy for monitoring tools, which could e.g. periodically call check
tasks and instead of parsing output, rely on exit code.

The way we detect if something failed is via hooking into String#red, and if
anything was ever printed in red - that's an error.

The default was switched to HTTP in the previous patch, but let's completely
remove SSH option - we support only HTTP for git fetch/push.

Both fetch and push are possible over https, which is selected by http if
gitlab was configured to use https in external url.

This way to reduce security vectors and possible ways to interact with gitlab
we use https only without ssh at all.

Escape HTML nodes in builds commands in ci linter

This MR removes call to `simple_format` that behaves like `String#html_safe`, thus it passes unescaped HTML tags to the view.

Enforce the fork_project permission in Projects::CreateService

Projects::ForkService delegates to this service almost entirely, but needed one small change so it would propagate create errors correctly.

CreateService#execute needs significant refactoring; it is now right at the complexity limit set by Rubocop. I avoided doing so in this commit to keep the diff as small as possible.

Allow the Rails cookie to be used for API authentication

Makes the Rails cookie into a valid authentication token for the Grape
API, and uses it instead of token authentication in frontend code that
uses the API.

Rendering the private token into client-side javascript is a security
risk; it may be stolen through XSS or other attacks. In general,
re-using API code in the frontend is more desirable than implementing
endless actions that return JSON.

Exclude some pending or inactivated rows in Member scopes

An unapproved request or not-yet-accepted invite should not give access rights. Neither should a blocked user be considered a member of anything.

One visible outcome of this behaviour is that owners and masters of a group or project may be blocked, yet still receive notification emails for access requests.
