Gustavo Jose de Sousa a6bdee076e ArduPlane: remove comments identifying task 
We don't need those comments anymore, now that we log the task name. Also,
keeping the comments means that we need to fix them when tasks are added in the
middle, not to mention the problem with tasks that are added selectively (i.e.,
guarded by preprocessor directives).
