Consider proc and cons of defining all app actions inside the code, not .fxml files

[introfog]

It is possible to define all actions in code, consider is it worth to do it in that way, or leave @FXML methods.

E.g. in com.github.introfog.gitwave.controller.main.MainController#runCommand you can avoid having method with @FXML annotation and can define clink action for run button which is already present in com.github.introfog.gitwave.controller.main.MainController.
