Changes in the Missions window and City Teleportation

[glavoljub]

1. The "Current Domain Only" mission filter has been replaced with a list of all player’s domains for easy switching between the missions from these domains. Also, filter "Show exploration missions" has been added. When the filter is disabled, the missions of the player’s explorers are not shown, but the missions of other players will be visible (for example, those who investigate a field where your hidden domain like Mine, Pit or Salt Lake is). When disabled, this filter will speed up the opening of the Missions window.

2. Each city can be teleported no more than once in 24 hours.
