A more detailed description of the "amount" field

The more frequent question I ask to myself when initiating channels regards the amount field.

In this document we have three different denominations and the modification proposed aims to address the possible doubts or errors.
The names <amount_in_bitcoins>, <amount_in_satoshis> or <amount_in_millisatoshis> (this last is omitted because the denomination is in the description) are not so elegant but they could serve the purpose.
