Improve UX flow for package entitlements

[KallynGowdy]

Currently, whenever a package want's access to an entitlement feature, it needs to manually request access via the os.grantEntitlements() function. In addition, when requested, the user is presented with a popup that doesn't explain much about what is being requested or who is requesting access.

Ideally, CasualOS would be able to automatically request entitlements on behalf of a package if it is recommended by the server. Additionally, CasualOS should display the following information in the "Grant Entitlement" screen:

• Package identity
  • recordName
  • address
  • version
  • hash
  • review status
  • approval status
• Package author identity
  • name
  • id
• Requested entitlement
  • Feature with explaination on what feature allows access to
  • recordName
  • duration with selector

Any additional factors that we can think of to provide the granting user additional context on the who, what and why would also be good to include.
