Optimize key selection when using "Write Dump (Clone)"

[arkdchst]

If I want to write dump to tag that has same keys as in dump stored I must wait key mapping process. I can solve it by exporting keys from dump to separated .keys file, but it would be better (?) to automate this process and optionally check keys from dump file first.

Thanks!

Fair. It is likely that if you do not copy a dump to a new tag (with default keys) you most likely writing it to the original tag. Therefore, using the keys from the dump first (right after the default keys) sounds reasonable.

This should go well together with #43. The approach for the quick dump/mapping features would be to select a dump file instead of a key file.

I'm not sure when I will have the time to implement it, but I add it to the todo list.
