Add Uninstal Option to Modules List

[MennaCC]

Story

As a user I can view available and installed modules, so that I can uninstall anyone I want

Suggested Acceptance Criteria

• installed modules can be viewed offline
• classifier is retrained after every uninstall
• if offline and a module is uninstalled, it shall be removed from the list
• if online, the module is removed and list of available modules on server are retrieved
• there should be no duplication between offline installed modules and modules retrieved from the server
• matching the offline to the retrieved module shall be based on name only for now

[[for further issues]] matching modules could use version too and add "update" option to the modules list
