Output cluttered with messages "Task <name> consumed ..."

[Chert-Nik]

I found this problem while working on this issue #20
Output of QDT launch is cluttered with messages like:
Task co_gen consumed 0.062391 sec during iteration between lines .../tools/qemu/qdt/qemu/project.py:162 and 181

Total number of lines printed during QDT launch: 6656
Number of lines of the specified type: 2738

Probably messages of this type should be displayed only when specifying a special flag that enables debug printing.
