    gtester-report: fix range usage when running as python3 app
    
    When using python3 as interpreter, range only takes integer arguments or
    it results in errors like:
    
       File "/usr/bin/gtester-report", line 78, in html_indent_string
         for i in range (0, (n + 1) / 2):
     TypeError: 'float' object cannot be interpreted as an integer
