fixed bitstamp bug
fixed MACD readme merge
Fixed issue with email password in configuration not being honored

The password in the mailer configuration was being ignored causing
problems when running gekko using screen (where you'd have to re-attach
the session to enter the password manually).
setupMail function expects an object with password
Properly set the scope of the setupMail function
No need to pass password to setupMail if it is not changing
added project status to readme
Email - use any SMTP server

Add config.js parameters for email server and user so not tied to gmail
etc.
