and the user can choose which one to enable and which one to skip.

Desktop: Add support for Pokéclicker-Desktop (issue #84)

The app.asar file was repackaged to load the pokeclicker-automation script suite.

Readme: Add known supported pokeclicker version

Farm: Add the Secret berry to the unlock feature

UserScript: add user-script

The userscript aims at loading any version of the automation.
To avoid any breaking changes, it was split into 2 files:
  - Automation-UserScript.js that will be used by the end-user
    and should never change
  - ComponentLoader.js that will be in charge of loading any
    needed js files and run the automation once loaded
