Move fountain/flag and victory check to end of action in 4th edition

[micahstairs]

Recent rule change: after the action, we should check for the fountains and flags before doing the victory check (starting with the player to the left of the active player). This means we will be checking it at the same time as the other special achievements (minus exceptions like Monument).

This also means that if a player reaches X achievements during an action, they have to wait until the end of the action before doing a victory check.

Number of achievements breaks ties before turn order does.
