[file specific changes]

DownloadMission.java
* remove redundant/boilerplate code (again)
* make few variables volatile

* simplify source stream init

DownloadManager.java
* move all "service message sending" code to DownloadMission
* remove not implemented method "notifyUserPendingDownloads()" also his unused strings

DownloadManagerService.java
* use START_STICKY instead of START_NOT_STICKY
* simplify addMissionEventListener()/removeMissionEventListener() methods (always are called from the main thread)

Deleter.java
* better method definition

MissionAdapter.java
* better method definition
* code cleanup
