Alpha 1.1.0  (ALPHA RELEASE VERSION)

NEW:
* Edited the images in About background and Direct scan controls
* Added new class GlobalExceptionHandlerActivity, which handles all
uncaught exceptions, logging them and restarting the application after 2
seconds.

CHANGES:
* Replaced all Activities' super class, from Activity to
GlobalExceptionHandlerActivity
* Replaced the TAG of all classes that has logging functions, removing
the whole package name, and it now only uses the class name
* Fixed the CheckLogs, it now uses asynchronous thread to read log
files.
* Fixed the logged information from DirectoryScanner,
FileDesignationScanner, FileDuplicationDetectionScanner, Alarm and
BootReceiver classes.
* Fixed the logging process in AndroidUtils. It does not append logs
from Scan logs and Progress logs anymore. Only Error logs are being
appended, to ensure that log files remain small in size.

NOTES:
* Codes inside MainActivity (line 530 - 539) produces a
NullPointerExcetpion but is not removed for the purposes of
demonstrating the GlobalExceptionHandlerActivity, by simply using a
non-existing username as an input in Login screen.
