Pull request description:
The rustdocs in the `units` crate has been reviewed and improved.
Some of the links were missing backticks, these have been added.
Some grammatical changes have been made to improve the documentation.
The use of links was inconsistent and has been changed to have links everywhere that seemed appropriate.
A couple of error headings were added and a description as to why a capital M is not accepted in the denomination for MegaSatoshi or MegaBitcoin.
