Description:
--------------------
Shows last damage/heal done by spell as button's text.

There is 3 types of more or less accurate spell effect you can expect by casting:

Tooltip data from Blizzard (seems always lower than actual effect)
Heavy calculations and tuning like DrDamage do
Collect data and show (like this addon)

For now supports only Blizzard's action buttons and Bartender4 since v0.20.

Howto:

To add damage/heal caused by spell's side effects:

Find "Target Dummy"
Enable debug mode like "/le debug"
Cast your spell and see log in chat
There will be cast and auras info, add your side effect spellId to LE_SpellPartOf in Spells.lua like = mainSpellId
"/reload" and see is it works
Disable debug mode typing "/le debug" again

Optional: uncomment "print(frame.action, bname, id)" (line 257 in v0.15) to print spell ids associated to action buttons

To toggle debug mode use slash command /le debug (or /LastEffect debug).
