Add some linguist-detectable attributes (#3806)

This allows to test a use-case where markdown should be reported
in the language stats (e.g because the main purpose of the repo is to
hold prose in markdown format) while HTML should be excluded from the
language stats (e.g because it's example output).

-***API UPDATE***
-
-Since [Version 3.0.0](https://github.com/github/linguist/releases/tag/v3.0.0) Linguist expects a git repository (in the form of a [Rugged::Repository](https://github.com/libgit2/rugged#repositories)) to be passed when initializing `Linguist::Repository`.
-
-
 ```ruby
-require 'rugged'
-require 'linguist'
-
-repo = Rugged::Repository.new('.')
-project = Linguist::Repository.new(repo, repo.head.target_id)
-project.language       #=> "Ruby"
-project.languages      #=> { "Ruby" => 119387 }
+project = Linguist::Repository.from_directory(".")
+project.language.name  #=> "Ruby"
+project.languages      #=> { "Ruby" => 0.98, "Shell" => 0.02 }
 ```
 
 These stats are also printed out by the `linguist` binary. You can use the
 `--breakdown` flag, and the binary will also output the breakdown of files by language.

-## Overrides
-
-Linguist supports custom overrides for language definitions and vendored paths. Add a `.gitattributes` file to your project using the keys `linguist-language` and `linguist-vendored` with the standard git-style path matchers for the files you want to override.
-
-Please note that the overrides currently only affect the language statistics for a repository and not the syntax-highlighting of files.

-
-By default, Linguist treats all of the paths defined in [lib/linguist/vendor.yml](https://github.com/github/linguist/blob/master/lib/linguist/vendor.yml) as vendored and therefore doesn't include them in the language statistics for a repository. Use the `linguist-vendored` attribute to vendor or un-vendor paths.

 Linguist has a number of methods available to it for identifying the language of a particular file. The initial lookup is based upon the extension of the file, possible file extensions are defined in an array called `extensions`. Take a look at this example for example for `Perl`:
