Sync dirs: different icons for different delete confirmation

[DrShark]

Currently when in Sync dirs in file's context menu we select to delete it by pressing
respective menu item, or respective menu item while pressed SHIFT key, we have different
behaviour: deleting to trash or complete removing.

However, the dialogs of confirmation for delete in both cases have same icons,
so it's easy to confuse them, just like it's easy sometimes to forget to press shift
or to press it not hard enough by mistake or because of bad on keyboard.

I suggest to make different icons in confirmation dialog for above cases, and the one
for complete removing must be red-coloured.

Windows Explorer BTW have good diffrerentiation in its confirmation for delete dialogs.

I agree that confirmation should mention how the files will be deleted.

BTW regular deletion may also be confusing when Recycle bin confirmations are disabled: in both cases (with or without Shift) TC shows the same confirmation dialog.
