Config files not working

[jolonf]

When starting echain as follows:

echain start -f ./event.json

It doesn't load event.json but instead searches for the first json file and may choose the wrong one if the directory contains other json files.

The issue is that the command line parsing uses fileconfig:

eventchain/index.js

Line 127 in 1147b53

fileconfig: 'f',

Whereas when it loads the file it is expecting config:

eventchain/index.js

Line 52 in 1147b53

} else if (options.config) {

Either config should be changed to fileconfig or vice verse.
