Currently the user is prompted for updates every time studio is started. There are, as of now, 4 possible titanium updates: cli, acs, alloy, sdk. There is no way to make any given update go away until the next stable update is released.
Steps to Reproduce:
1. Delete SDK, CLI, Alloy, and Node.ACS.
2. Restart studio.
Prompt for install on startup. Prompt for updates after a few minutes.
If an update was deselected, the update prompt should not show up.
