Allow more than one controller to attach OnFocus/OnFocusLost functions

Browse Source 
Trying to do this would previously have the second one silently overwrite the
first one's.

We don't currently have this in lazygit, but I ran into the situation once
during development, and it can lead to bugs that are hard to diagnose.

Instead of holding a list of functions, we could also have added a panic in case
the function was set already; this would have been good enough for the current
state, and enough to catch mistakes early in the future. However, I decided to
allow multiple controllers to attach these functions, because I can't see a
reason not to.
