Added suite_field_formatter option and fixed a couple display issues when suite_names = false

[chiliburger]

Added suite_field_formatter option to have more control over whitespace without forced newlines except before the suite name. Now you can have 1 line output for each suite name if that is your preferred output.

Sample suite_field_formatter => " | %s" # creates nice 1 line output Sample suite_field_formatter => "\n %s" # creates nice multiline output

Also fixed an exception where the suite_names was set to false and the wrap_count was trying to be decremented. Fixed display issues when suite_names was set to false.
