chifra names: Incorporate the functionality of addName into chifra names

[tjayrush]

In order to add or edit names I use this terrible shell script:

#!/usr/bin/env bash

# addName - adds a name to the names database

defSource="Etherscan"
defDecimals=""

ADDRESS=$1
echo -n "Enter an address: "
if [[ -z ${ADDRESS} ]]
then
    read ADDRESS    
else
    echo $ADDRESS
fi

NAME=$2
echo -n "Enter a name: "
if [[ -z ${NAME} ]]
then
    read NAME
else
    echo $NAME
fi

TAG=$3
echo -n "Enter a tag (def: 30-Contracts): "
if [[ -z ${TAG} ]]
then
    read TAG
    if [[ -z ${TAG} ]]
    then
        TAG="30-Contracts"
    fi
else
    echo $TAG
fi

SOURCE=$4
echo -n "Enter a source (def: EtherScan.io): "
if [[ -z ${SOURCE} ]]
then
    read SOURCE
    if [[ -z ${SOURCE} ]]
    then
        SOURE="EtherScan.io"
    fi
else
    echo $SOURCE
fi

# These will be set by querying the chain
SYMBOL=$5
DECIMALS=${6:-$defDecimals}
DESCR=$7

echo "---------------------- Adding -----------------------"
echo "Address: " $ADDRESS
echo "Name: " $NAME
echo "TAG: " $TAG
echo "SOURCE: " $SOURCE
echo "DECIMALS: " $DECIMALS
echo "SYMBOL: " $SYMBOL
echo "DESCR: " $DESCR

export TB_NAME_ADDRESS=$ADDRESS
export TB_NAME_NAME=$NAME
export TB_NAME_TAG=$TAG
export TB_NAME_SOURCE=$SOURCE
export TB_NAME_SYMBOL=$SYMBOL
export TB_NAME_DECIMALS=$DECIMALS
export TB_NAME_DESCR=$DESCR
~/.local/bin/chifra/ethNames --create
cp -pf "$HOME/Library/Application Support/TrueBlocks/names/names.tab" "$HOME/Development/trueblocks-core/src/other/install/names/names.tab"
chifra names --all --expand $ADDRESS

This was always supposed to be part of chifra, but we never added in a --add (or --edit) option to chifra names. Documenting here as this will be part of the port to Go code for ethNames.
