cellSaveData* progress & reverted commit 950fcfe

* Reverted commit
https://github.com/DHrpcs3/rpcs3/commit/950fcfe4ef6da8aad5198fc12b029862545cfc4e
(Reverted ConLog changes) that fixed the "Bad flip!" error since there
is a better way of solving it. It will be fixed soon.
* Moved cellSaveData to cellSysutil (but preserving the functions in a
separated file named: cellSysutil_SaveData.cpp).
* Progress on cellSaveDataList* functions.
* Added a small margin to the new Settings dialog. :-)
