Buildmode & GM panel compatability

[Doubleumc]

About the pull request

Allows multiple click intercept sources (ex/buildmode, GM panel, rappel panel) to coexist peacefully. It remembers all sources and the most recent source takes priority.

Instead of a single click_intercept, there's now a list of click_intercepts. Any activated intercept source will add itself to the list, and will remove itself when deactivated. The last source in the list (the most recent) gets the clicks.

Significantly adjusted how the GM panel handled its multiple intercepts to work with the new system. Should be the exact same for the user.

Explain why it's good for the game

Buildmode and the GM panel are used every round, frequently at the same time. This PR allows them to be used side-by-side in a much smoother way than one nuking the other's click intercept if that control is closed.

Testing Photographs and Procedure

Boots without issue. Tested having buildmode, GM panel, rappel panel all open at the same time. Closing one allows the others to still function.
