HTTT: add wmllint: recognize Simyr

wmllint tries to detect errors such as a scenario author forgetting to introduce a unit via [recall], [unit] etc and then referencing the unit by id.

Simyr is added to your recall list if you beat 02_Blackwater_Port on HARD by killing the orc leader.

In this instance the scenario author not automatically recalling Simyr is clearly intentional.
