Fix #403

This PR includes the following:
- Fix issue with daemon-rpc example styling.
- Remove references to deprecated class “cli-code” and replace with
code blocks where necessary.
- Add new line between all RPC calls and outputs.
- Use 3-apostrophe code blocks instead of indent for all curl examples
for markdown neatness and to enable future syntax highlighting.

The proper CSS class was changed from "accordian" to "accordion". The "If Monero is so private how do we know they're not being created out of thin air?" section got left out when the change was made which results in the ugly default checkbox being used instead of rehrar's custom CSS
