Shows alerts before addspawns in eidelon NM, and on matching AEGIS eruption in flappy NM. This happens in the following way:

10, 5, 4, 3, 2, 1 seconds before eidelon add-spawn the mod will beep and show a big red message.
Right before spawn it will double-beep.

When flappy casts AEGIS Eruption, and for four seconds, the mod will beep and show a big message.
For five seconds before the eruption, the mod will beep and show a message again. Roughly around eruption it will double-beep.

The mod can be disabled in eidelon and flappy individually by doing the following:
/setoption EidelonHelper_Eidelon false
/setoption EidelonHelper_Flappy false
