Describe return fields of RPC call 'sendrawtransaction'
closes #224

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.
