gsync: Display additional information in status command

Added code to display extra information when status command
is executed.
 Information shown now are
1 Number of files synced
2 crawl time
3 total sync time
4 bytes synced

bytes synced is taken from rsync output .
--stats option of rsync gives extra infor
mation about the sync.In stats output there
is a field called Total transferred file
size which states the ammount of bytes synced .
This information is parsed from stdout output
using regular expressions.Bytes synced information
can be used to calculate throughput.
