Selected squads cause vanilla achievements to look buggy

[KnightMiner]

Due to how selected squads work, vanilla achievements show the wrong title and tooltip, but the correct icons:

We should detect when the achievements menu opens and undo our title override/tooltip override. When paired with #167, this will ensure all achievements are visible.

I am having difficulty identifying when the two different tabs are open. It appears to me that the same text is used for both the button and the title.

Hangar_Achievements_Title = "Achievements"
Button_MainSquads = "Squads"
Ach_Global = "Global"

Until someone can find a way to detect when either is open, this issue is blocked.

We could honestly just detect when either is open, its not a huge deal if we are on the global achievements page and we disable our overrides. That said, it will make #167 more difficult to handle if we cannot tell which is which

So perhaps just have an achievements UI open event/getter, and if that getter returns true, skip the title overrides.
