unity launcher doesn't respect webapp configs through updates

[Jane Silber]

When applying updates to a 12.10 install, the unity launcher re-introduces items, specifically the default webapps of Ubuntu One and Amazon, that I have previously removed. I have seen this (incorrect) behavior on webapps. I do not know if it happens for native default apps.

Expected behavior: Ubuntu policy is to respect user configs through updates and upgrades. If a user has removed default items from the launcher, the update should not reintroduce them.
