buttons in copy/move conflict dialog

[oko]

Let me suggest better organizing of buttons in F5/F6 conflict dialog.
Now there is mix and some of them are in submenu.
Logic is to differ critical and non-critical actions and direct access to all (no submenus because confirmation should be quick). Critical actions cause unrecoverable loss or change of at least one of files. Non-critical actions do not cause loss, all files are retained.
So there can be two columns of buttons:

1. Critical:
- Overwrite
- Overwrite all
- Overwrite all older
- Overwrite all older and same age
- Overwrite all smaller
- Overwrite all larger
- Append

2. Non-critical:
- Cancel
- Skip
- Skip all
- Compare
- Rename...
- Rename existing target file...
- Auto-rename all copied
- Auto-rename all target files


Notes: Some of captions are renamed according to logic of the other. Some of captions are with dots because user will be prompted to write name.

You can consider to differ action for actual conflict and action for all the same conflicts, so there can be 4 visual groups of buttons:

1. critical + per file:
- Overwrite
- Append

2. critical + repeated (for all files with the same conflict):
- Overwrite all
- Overwrite all older
- Overwrite all older and same age
- Overwrite all smaller
- Overwrite all larger

3. non-critical + per file:
- Skip
- Compare
- Rename...
- Rename existing target file...

4. non-critical + repeated (for all files with the same conflict):
- Cancel
- Skip all
- Auto-rename all copied
- Auto-rename all target files
