Add Statistics columns to Log window and Commit window

To be able to easily scan for significant commits or files, please:

1. Add to Log window columns for (Added Lines) and (Lines) similar to "git log --shortstat"; A graphical column as in "git log --stat" would also be welcome.
   
2. Same in Commit view for each file similar to "git log --stat" and "git log --numstat"

      3. Size of changes in KB would be great for scanning for large binaries, but I cannot provide a command line equivalent.
