a9c00a05fe HTTP -> Http 
Change the capitalisation of HTTP to Http, to conform to the QL style
guide.

Leave the HTTP module in Concepts alone, so it remains consistent with
the Concepts in other language libraries.

3a4ddc4b4e Model the HTTParty http client 
We currently model direct calls like

    HTTParty.get("http://example.com")

but we don't yet handle calls on other classes that have included the
`HTTParty` module, like

    class MyClient
      include HTTParty
    end
    MyClient.get("http://example.com")

This query finds cases where user input flows to an argument to `eval`
or `send`, which can execute arbitrary Ruby code.

739661eb10 Test that KernelMethodCall is specific enough 
Calls to `UnknownModule.system`, where `UnknownModule` is a module that
we know nothing about, should not be identified as instances of
`KernelMethodCall`.

f8359767bc Exclude non-shell interpreted args 
Update the CommandInjection query to only consider sinks where the
argument is interpreted by a shell. If the argument is passed directly
to a subprocess then it's not vulnerable to shell injection.

cbc14ccda9 Make KernelSystemCall more specific 
Test that calls to`system` on modules other than `Kernel` are excluded,
such as in this example:

    module Foo
      def self.system(*args); end
    end

    # This is not a call to Kernel.system
    Foo.system("bar")
