Jonsba/master (#100)
* Add a --unbuffered option for simulation. It disables buffering for stdout, stderr and files opened in write or append mode (TEXTIO).
Fixes #87
* Some simplifications made on the previous commit. Documentation added for --unbuffered in Simulation_and_runtime.rst.
* Some more simplifications on unbuffered writes support for TEXTIO
* Fix a style issue failure reported by Travis-CI
