Rename "Zotero Style Repository" and move to citationstyles.org domain

[rmzelle]

There are several journals that incorrectly present CSL styles as being Zotero-specific. See e.g. http://www.malariajournal.com/authors/instructions/research#formatting-references :

Style files are available for use with popular bibliographic management software:

• BibTeX
• EndNote style file
• Reference Manager
• Zotero

and http://www.uk.sagepub.com/msg/ta.htm#ReferenceStyle :

If you use the Open Source program “Zotero”, please use the style allotted to the Journal of Molecular Biology.

As much as I appreciate Zotero's efforts in creating and maintaining the Zotero Style Repository, I think it would be much better to rename the page to something like "CSL Style Repository" and host it at citationstyles.org (and set up a redirect for zotero.org/styles).
