Shuffling several apps

This code is updated for working with the recent (>3.0.8).

to make it work, do 2 things:

1. Add StartApp at the beginning of app_sequence of the session config where you want to randomize apps (all following apps will be randomized, with an exception of StartApp)

2. in each pages.py instead of

from ._builtin import  Page

insert

from StartApp.pages import Page

You can keep the old import statement and insert a new one after that:

from ._builtin import Page, WaitPage
from StartApp.pages import Page
