fix donation/import/sort utility command line options

[smithcferg]

I am so grateful for all the work that you put in on this. Big shout out to Pierre for his work on import/sort utility.

1) I made a donation to https://www.xnview.com/en/xnviewmp/#downloads->DONATE button. The onfastspring.com website treats it as a taxable cost and takes almost a tenth for tax, which also means that Pierre gets less. Maybe there is a way that this can be improved so taxes aren't charged on donation. Pierre should get every penny!

2) I would like the import/sort utility to be callable through batch files using command line arguments, without opening xnviewmp. This allows multiple downloads of memory cards without having to open/close xnviewmp.

I would definitely give more for this.

Thanks,
Craig
