New actions format

[heynemann]

Allow users to specify actions as:

@action('And I click something')
def click_something():
//click something

This would reduce A LOT the noise generated by actions. A lot of repeated code would just go.

I think you already know that, but it should be nice to have a context and arguments, just like current actions.

@action('And I click (\d+) times on (?P<element>\w+)')
def click_x_times_on_element(context, num, element):
    // click n times...
