- The last part of the module import path is the module name. This also
becomes the Django app name. Apps names have to be unique. Hence,
there is no scope for two different modules with same name but
different load path to exist in the project.
- Most uses of list of loaded modules are dealing with app names instead
of full module load path. This is due to the fact that Django deals
with app names and not module paths.
- It is also somewhat clumsy to access a loaded module as we are
re-importing every time to get access module.
- Simplify all of the above by using app names are module identifiers
and maintaing an ordered dictionary of app names to loadded modules.
- Remove unused imports.
- Minor styling fixes.
- Change term 'reboot' to 'restart' as it is less techinical and more
consistent with popular interaces on desktop/mobiles.
- Updated description for power module.
- Simplify the module title to just 'Power'.
- Update the use of elipses and angular quotes as angular quotes and
elipses are both used to indicate that further user interface will be
available after pressing the button.
- Remove suprious '\' in power_reboot.html.
- Notify to the user that web interface will not be available after
reboot/shutdown.
- Redirect the user to application page after restart/shutdown. If the
page serve succeeds, they will have simply refresh/access it after
restart/shutdown after waiting or powering on.
