improved unittests for the core parts, removed module definitions and some minor other stuff

 - updated the visual studio to 2013 update 1 (changed sln version)
 - added solution settings for web essentials 2013
 - removed all module/export declarations in the typescript code because of bad tooling support (smart type completion cannot infer modulename)
 - new IAction interface
 - simulationHistory now stores the actions for each round instead of state copies
 - improved test coverage on simulationHistory, SimulatorFactory
 - added auto refresh to SpecRunner + time of document load
