Issue-142 : added time estimation and bandwidth indicator to the systry and active download
Issue-#142 : Added support  for current file completion estimation.
Changed the account settings estimation to display both current file and overwhole estimation.
Decresed the progress font size to fit the added information
Fixed Indentation and multiple concurrent files syncing case ...
..Also increased the height of folder progress bar alittle in order to accommodate the added estimation data
Seperated the systray estimation text to a seperate action, fixed an integer rounding bug
Made the estimated time only appear in the systray when the sync has actual size.
Changed the time estimate string to be more textual, also added lower limit to the estimate to prevents starting estimation jittering
changed the  systray  to  display total size  and  estimated time  when the  syncronization actually has size changed the  descriptive  time logic to be more generic
made the time description more malleable ,added support for none size update estimation (ie.. deletion), made the estimation more responsive at start  and less jittery after some time
better time prediction
Remove extra space between the parenthesis when displaying estimation in the system tray
made the code a little cleaner
chaned the design a little
added "/s" to the bandwidth
fixed comment spelling
change the mapping to use short hand and also  made the mapping logic a little losser
change the text to be a little more descriptive and use shorthand in the context menu
