Port to Python 3

[quozl]

A mandatory requirement for porting this activity is two laptops with embedded microphone and speakers, and a wireless network between them. Sugar and the activity must be run natively. Using VMs is not an accurate test, as it is not representative of the equipment the software is written for.

• write a test plan that includes measuring distance as above, then execute the test plan and measure coverage,
• measure specific distances using the Python 2 source code,
• rewrite the existing TelepathyGLib port to use D-Bus, as per the Python 3 Porting Guide,
• bug fix and iterate until test plan completes with appropriate coverage.
• Port to Python 3,
• bug fix and iterate until test plan completes with appropriate coverage,
• measure specific distances again, and confirm the distances are unchanged.
