proprietary-files: move apps to reflect lollipop paths

system.prop: Disable Atlas service.

Disable Atlas service to avoid memory overhaed caused by it.

Drawbacks in Atlas service:
- Fixed size of canvas: whether the drawebles are in use or not always
                        resides in memory.
- Choosing drawables: It chooses the drawables to pre-load based on
                      dimensions, rather than number of requested apps.

system.prop: force high-end graphics

UX is just brutal on low RAM devices. There is no background
on the lockscreen (just blank black screen) and no shade in
the notification area (screen turns black immediately when
start pulling down notifications). Force high end graphics
until these issues are sorted and if/when there's an user
option to do this.

system.prop: fix starting background processes prop

Fix property introduced in commit fddccf81885496fbf53c92fb1471fc4b3dfecf26 -
no such thing even exists. Allow more background services (8 - normal,
4 - forced here, 1 - on low_ram) during booting on low memory devices.
This fixes e.g. a huge delay before SIM PIN screen is displayed on low
RAM devices.
