Add new service classes to create and update project and personal
snippets.  These classes are responsible for enforcing restricted
visibility settings for non-admin users.

Allow admins to use restricted visibility levels when creating or
updating projects.

This commit generalizes the image upload via drag and drop so it supports all files.
It also adds access control for these files.

Make the following changes to deal with new behavior in Rails 4.1.2:

* Use nested resources to avoid slashes in arguments to path helpers.

Resolves #1673.

adding avatar to project settings page added avatar removal show project avatar on dashboard, projects page, project page added rspec and feature tests added project avatar from repository new default project icon added added copying af avatar to forking of project added generated icon fixed avatar fork hound fix style fix test fix

Instead of loading all issues and merge requests we load only open one.
This will reduce time load for autocomplete resources significantly

Always delete repositories from the filesystem when deleting a project.

Update the project API controller to use `Projects::DestroyService`
instead of calling `Project#destroy` directly.

Also add an optional parameter, `:keep_repo`, that allows a project to
be deleted without deleting the repository, wiki, and satellite from
disk.

Remove overload of BaseService.initialize, so initialize gains params,
which is used to pass the namespace (like e.g. in TransferService).

The namespace is checked for permission to create projects in it.
