* Timers now are Application thread safe * Timers now have consistent API independend of Application (no more c style timers) * Timers can have either: callback or override onTimer() method - this way we can create more complicated timers or just use existing ones * gui::Timer added via adapter class GuiTimer to decouple sys::Timer with gui::Timer * Fixed race in wrapper * Updated docs * fixed using std and cpp_freertos and DataReceivedHandler hidden in Application.hpp
