Run stripping for other any or all modes when running on MC

What are your thoughts on this implementation before I add the remaining lines?

Now the mode information is being passed to the DaVinci job should we prevent  the creation of Cheated/MCTupleTool trees when using MC from other modes?
Might I suggest
```python
# Is the MC minimum bias?
minbias = tags.mode() == '30000000'
# ...
if minbias or tags.mode() in ('21163020', '21263010'):
    # ...
```
As that minimum bias check will be made for every mode.
