Drawer Updates

Updates to the Drawer UI components to allow removal of all option menu items, the
tracking functions are now available through the first section of the drawer. Items
will dynamically update to reflect the current status of the tracking item and
FemtoCell tracking will only be shown for CDMA devices.

Moved the all the classes & interface files into a dedicated package folder to make
maintenance easier.
OpenCellID Download Progress Bar Fix

Corrected the RequestTask class to correctly show the progress bar for downloading of
OpenCellID data, contentlength method was returning -1 as filesize of the download
is unknown so the maximum size of the progress bar was being set to that value
resulting in the progress bar no displaying anything.
CID & LAC Fix

Reported that some devices are returning both the CID & LAC as INTEGER.MAX value,
included a check for this and possible correct by using 0xffff bit-mask if this is
returned.

Awaiting user testing to confirm correct CID & LAC are now being returned by these
devices.
AT Command Timeout Option

Added another spinner to allow selection of a number of timeout values to assist with
receiving the AT Command response, values currently available are: 2, 5, 8, 10 & 15
seconds.
