File size informations in synchronization

[HBB]

In synchronization, I believe that the followings will be helpfull :

- total sizes of files which will be copied and deleted take place at the bottom of comparison dialog before pressing synchronize button.
- total sizes of files which will be copied and deleted change simultaneously at the bottom of comparison dialog while users check or uncheck the file list items.

- total and remaining sizes of files in copying and deleting dialog while synchronization (after pressing synchronize button and after passing confirmation dialog).
