Re-levelization: move non-docs content, rename content→docs

For better URLs, the content folder has been renamed 'docs' and all
other files have been moved up a level. Also, non-docs images have been
moved to the static folder at the top level where they belong.

Many relative paths had to be fixed to make this work.

 This tutorial explains how to send a direct XRP Payment using `xrpl.js` for JavaScript, `xrpl-py` for Python, `xrpl4j` for Java or `XRPL_PHP` for PHP. First, we step through the process with the [XRP Ledger Testnet](../../concepts/networks-and-servers/parallel-networks.md). Then, we compare that to the additional requirements for doing the equivalent in production.
