Source Code Compare Todo:
1. Context menu on left and right memos with such items: copy line (to clipboard); copy selection (to clipboard), update left .pas (change left file as on right), update right .pas. And implementation of this menu items
2. When run comparing via F9 expert shoud reload .pas files (or check that they are not changed since they are loaded). I seek change, modify changes, save updated pas. Run comparison again and there are no changes.
