GSOC 2019 : Improve smbcmp - Week 3

[P Mairo]

Hello, a summary of my activities for the last week :
- Made the code 'debugable' : basically wrote a function which clean the
curses screen when I debug using pdb because it was impossible otherwise
- Added a color highlighting when the content of the packets are the same
in the diff view
- Started the exploration of the XML output of Tshark
