Title: add _ placeholders to _.partial

This commits adds the ability to set a palceholder for the _.partial functions on the parameters. Which I feel is pretty much a required feature for a 'partial' function.

Searched previous issues before creating this pr and found: #1163. Feature was requested but no pr was ever submitted. Here's my implementation. Does not effect the speed of _.partial method which does not make use of placeholders.
