Update CMakeLists.txt

Remove explicit dependency on gfortran (through -lgfortran). Since no absolute path is specified, our test machine (Ubuntu 12.04.1 32bits) was failing to resolve the library.
Corrected commentary in thread_interruptible_loop.py
Added explicit set of velocity in device.cpp
[travis] Add Travis and coveralls.io support
[travis] Fix push URL
Update README.md

[skip ci]
Remove unwanted files.
[travis] Add push token
Synchronize
Rename test traces into test_traces.

Before this commit, it was impossible to build the project in-place
(without a separate build directory) as the traces directory and
traces test were conflicting in unitTesting.
