Document partial build functionality

[benjamingr]

Adds a description of how to make a partial build of Ramda, closes #806

I will create a separate PR for the docs repo as it's in a different repo. Note I've also included the /docs fix here.

Hey, in first look it looks like the index file in the docs repo is generated from the README.md file here - is this the case or should I submit a separate PR for the docs repo?

i'd say that the functions in the description should match the functions in the example. So the preferable way to go is probably to remove src/curry.js and src/map.js from the example

Roger. Editing.

no need to pr vs. ramda.github.io

@buzzdecafe thanks. In that case the PR is done - you can merge it if you'd like.

Great work on the library, having something powerful like this in JS is really refreshing, as someone who's never seen the point of underscore given the native methods this has shown me a new light :) Asked that question and started this PR since we're actually deploying an internal app using Ramda. Thanks again for saving me time by making the library.
