Add DBM_TimerUpdateIcon event listener

[QartemisT]

Description

DBM timers can call :UpdateIcon which will replace the default icon state from when a timer is started. This fires the DBM_TimerUpdateIcon event, and any WeakAuras that have listened to what the icon is should update the icon to reflect these changes.
The DBM_TimerUpdateIcon is newly implemented in DeadlyBossMods/DeadlyBossMods@5e75945

That still isn't enough, no one is reacting to these events. I would finish the PR, if you tell me how to reproduce the issue easily.

I've updated the description of the issue to reflect the intended purpose, and that it's adding new capability.

That doesn't tell me how to reproduce it the bug that handling that event fixes. How can I create a test that makes dbm fire that event?

-- Create dummy mod
local dummyMod = DBM:NewMod("WeakAurasDummyMod")

-- Create initial timer
local timer = dummyMod:NewTimer(60, "Test", "136002")
-- Start time (Fires DBM_TimerStart event with icon 136002)
timer:Start()

-- Update the icon
timer:UpdateIcon("132486")

Is the example test mod. In this case, the default state for icon would be 136002, and upon updating the icon, it's changed to 132486, however WeakAuras doesn't see that the icon has updated.

The events that should be fired in total are;
DBM_TimerStart - args: Test, Test, 60, 136002, cd
DBM_TimerUpdateIcon - args: Test, 132486
