1. set default option '-h' [why] the tool will show help message if no option specified the tool will get no email address without both '-e' and '-f'

[how] add '-h' as default option if no option specified options will be reset to '-h' if both '-e' and '-f' are not specified

2. fix undefined method 'empty' [why] the original value is defined 'nil' for my_email when execute answerback-email with no '-e' or '-f', it will throw error as: raceback (most recent call last): 2: from ./answerback-email.rb:213:in `<main>' 1: from ./answerback-email.rb:184:in `send_account' ./answerback-email.rb:155:in `check_my_email': undefined method `empty?' for nil:NilClass (NoMethodError)

[how] use '.nil?' instead of '.empty?'

3. option parse error [why] if add no required value for option, the option will use the field that follows as its value. example: ./answerback-email.rb -e -n name Not a standard format email: -n.

[how] add value check for options that need a value
