When we build a note URL, and we have the note loaded already, there are two
cases:

1. The `noteable` is already loaded. In that case, this is faster as it doesn't
   build a new AR object from the query.
2. The `noteable` is not already loaded. In that case, this change is no worse
   than the previous code.

Adding the necessary API for the new /snippets Restful resource
added with this commit. Added a new Grape class `Snippets`, as
well as a `PersonalSnippet` entity.

Rails' "url_helpers" method creates an anonymous Module (which a bunch
of methods) on every call. By caching the output of this method in a
dedicated method we can shave off about 10 seconds of loading time for
an issue with around 200 comments.

Also, streamline the view.

Closes https://github.com/gitlabhq/gitlabhq/issues/9605

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.

Supports four different event types all bundled under the "note" event type:

- comments on a commit
- comments on an issue
- comments on a merge request
- comments on a code snippet

Previously the symbol "url" in the object_attributes hash would always be nil.

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.
