The White Rabbit's Sequencer

version 1.38 : 

a lot of improvement for macros. in a command /cast [@unit1] spell1, [@unit2] spell2, etc...
now the spell1, spell2 ... are identified to the book spells, and share their parameters, cooldowns, charges, etc. An hint/information has been added next to the label "Sequencer".

the units inside a macro are remapped by SortUnitFrames, for example you can use : tanktarget to cast all your spell to the tank target.

consequently, cast time, GCD and aura are now a shared parameters (was step parameters).

added an unit label for the HUD.

fixed an embarassing bug where the validation of the import didn't work.

the cut before the end time due to the SpellQueueWindow CVar has been multiplied by 3 (3 x SpellQueueWindow in milliseconds), to avoid casting twice the same spell whereas TWRS push the right spells. A value of 100ms for SpellQueueWindow gives good result to me.
