Make token selection sensitive to the score type selected

[privong]

For example, abbotts cannot score roads. So if roads are selected as an option, don't show the abbot as a token choice.
This will require some re-working or enhancement of the underlying database.

With commit 0e112d4, the order of entries has changed. So now this should be implemented by seeing which token was selected and then only showing tile/scoring types that are compatible with that type of token.

When the "Traders & Builders" expansion is used, the score type of "Trade token" is added. But that score is not associated with a token type. This suggests that the score type should be input before the token type. Thus, in order to address this issue, the score type (road, meadow, etc.) should then limit the token types that can be chosen. Thus the mappings recorded should be the score type -> token type as initially suggested.
