Add options for 'no-unused-vars' to check all arguments in functions (fixes #728)
Add global cli flag (ref #692)

Adds a --global cli flag to define global variables. To define
multiple variables, either separate them using commas, or use the
flag multiple times. By default, all variables are read-only, but
appending `:true` to the name will mark it as writable.

Example:

    eslint --global require,exports:true file.js
    eslint --global require --global exports:true file.js
Rule: valid-typeof

For a vast majority of use-cases, the only valid results of the `typeof` operator will be one of the following: `"undefined"`, `"object"`, `"boolean"`, `"number"`, `"string"`, and `"function"`. When a user compares the result of a `typeof` operation against a string that is not one of these strings, it is usually a typo. This rule ensures that when the result of a `typeof` operation is compared against a string, that string is in the aforementioned set.

    typeof foo === "strnig"

Fixes #715
