More Xeno Alliances Tweaks

[ihatethisengine]

About the pull request

1. xeno_message no longer sends the message to allied hives.

2. All hive's alliances break on Queen's death (instead of essentially just ceasing to function).

3. If another hive breaks alliance with you, you break alliance with them automatically.

4. Some code improvements.

Explain why it's good for the game

1. Less confusing. I meant to add a "notify_allies" var to the proc, but I haven't found a single message that should be sent to allies.

2. Less confusing. Essentially all alliances already don't function if queen is dead, so this way it's just more clear for everyone.

3. You don't have to keep hive alliance status open all the time in case allied queen decides to betray you. Simply a QoL.

4. Just good
