Merging attributes page into Manipulating Elements

[connorcartwright]

Hey guys @AurelioDeRosa @agcolom

Following the comments made in issue #642 by devs4u I’ve merged the attributes page into the manipulating elements page.

I've added some line spacing and moved around the text a bit in the Manipulating Attributes section. I also added in a sentence from the old attributes page and a getter code example.

Let me know if you have an feedback or if there are any problems and I'll get on it asap :bowtie:

Hey @AurelioDeRosa

No problem, thank you for the feedback!

I've removed the line spacing between those two sentences and added a link to the .attr() api page on its first mention.

Would it be best to add the attributes.md file back in and give it a meta tag to redirect, something like:

<meta http-equiv="refresh" content="0; url=http://learn.jquery.com/using-jquery-core/manipulating-elements/" />

Or is there a simpler way I'm missing?

I think we might have a process in place for these situations but I'd like to have our expert opinion @gnarf
