Unmoored Ego | The Brain Stone | Ancient Vendetta exiles any number of basic lands from library

[jam736]

This is more of an issue with SearchTargetGraveyardHandLibraryForCardNameAndExileEffect specifically in the applySearchAndExile. If a basic land is named the count limit is correctly incremented when searching the graveyard and hand. When the library selection occurs, any number of cards can be selected with the basic land name regardless of how many were previously selected from the graveyard and hand.

Example:
init.txt file

[ancient vendetta]
@init
hand:Human:Ancient Vendetta:4
graveyard:Computer:Forest:3
hand:Computer:Forest:3
library:Computer:Forest:10

Steps to reproduce

1. Activate the [ancient vendetta] cheat (above)
2. Cast Ancient Vendetta targeting opponent
3. Choose basic Forest
4. Select 2 Forest from the graveyard
5. Select 2 Forest from the hand
6. Select any number of Forest from the library
7. Look at the exiled number of cards and it will be the total cards selected

The problem is that we've 1) run out of legal targets, but 2) need to show the opponent's library to the player because they're allowed to search their opponent's library and in paper they could search the graveyard, hand, and library in any order. This triggers a search with 0 maximum targets which allows the player to choose an infinite number of targets. There needs to be some refactoring done to guarantee that 0 maximum targets is "show the choices but don't allow anything to be chosen" and use MAXINT for actual infinite targets.
