Allow `_.trim`, `_.trimLeft`, and `_.trimRight` to remove specified `chars`.
Avoid using a unique key for `keyPrefix` as it causes issues when lodash is modularized into individual npm packages. [closes #446]
Update vendors.
Add doc note to `_.bind`, `_.bindAll`, `_.partial`, `_.partialRight`, and `_.curry` about not setting the resulting functions `.length`. [closes #444]
Make the guard checks in `_.assign` and `_.defaults` more thorough.
Make `_.isEqual` work with plain objects containing `constructor` properties with like object values and make `_.invert` assign arrays when using the `multiValue` flag. [closes #420]
