Favorites should not be reset

[TheConstructor]

In maintenance/loadtweets.php#L154 you reset the favorite-flag of all tweets to 0.
I understand that there is a problem handling revoked favorites but reseting alls favorite-markers will lead to trouble if:

• you have multiple users only the favorites of the last user are stored at all
• you have more favorites than twitter wants to show you (and these scripts are meant as a work-around to just this kind of limitation, right?)

If you stored favorites like suggested in #2 you still would be able to revoke (at least some) favorites if you still fetch all favorites you are offered, otherwise I am unsure whether conserving as many favorites as possible is more important or allowing revocations.
Allowing multi-user-favorites seems to be impossible without storing any information about the individual favorites.

Keep the good work up!
