more fixes

* use bold style in status (mission_item_linear.xml)
* fix download attemps not begin updated
* dont stop the queue if a download fails
* implement partial wake-lock & wifi-lock
* show notifications for failed downloads
* ¿proper bitmap dispose? (DownloadManagerService.java)
* improve buffer filling (CircularFile.java)
* [Mp4Dash] increment reserved space from 2MiB to 15MiB. This is expensive but useful for devices with low ram
* [WebM] use 2MiB of reserved space
* fix debug warning if one thread is used
* fix wrong download speed when the activity is suspended
* Fix "Queue" menu item that appears in post-processing errors
* fix mission length dont being updated (missing commit)
