yampa: Conformance with style guide

[ivanperez-keera]

Description

Several files inside yampa/ are not conformant with our own style guide. These are mainly in the examples directory.

A quick search shows the following potential violations:

3 File structure, no blank lines at top
./examples/yampa-game/MainWiimote.hs

./examples/TailgatingDetector/TailgatingDetector.hs
./examples/Testing.hs
./src/FRP/Yampa/InternalCore.hs
./src/FRP/Yampa.hs

Notes
Many of the lines over 80 should not be broken down at this point. They may contain links or sessions and those should be kept as they are.
