Bug: Unicode headers prevent script from running

[LukeShirnia]

Hey.

We regularly get issues with the traffic analyser not running on device with errors similar to:

Traceback (most recent call last):
  File "<stdin>", line 1885, in <module>
  File "<stdin>", line 1854, in main
  File "<stdin>", line 1652, in print_main_header
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-10: ordinal not in range(128)

A very simple solution of emptying the headers works. Eg:

class Title(object):
    line = u''
    traffic_analyser = u''
    log_info = u''
    log_result = u''
    general_info = u''

Ill look into more appropriate fix when I get a chance.

This works for me:
