Previously, add_list_option() used argparse's "append" type. Now it uses nargs='+' to allow multiple options (space separated) that also override defaults rather than appending.
Added a stream readlines() function to read all lines into a list.
Added fformat() function, giving plugin authors more access to variables.
Fixed "Curl Robots" plugin (suggestion by Alh4zr3d) so it only saves the robots.txt file if it finds one.
The manual commands function will now merge command arrays instead of replacing them, while removing duplicate commands and preserving order.
Added a default option to get_global / get_global_option function in case user deletes global options.
Updated several plugins that use global options.
Switched spaces to tabs throughout for consistency.
Changed add_port_match() to match_port()
Changed add_service_match() to match_service_name()
Removed un-used variables.
