* Update intro.md
Significant clarifications, especially in the paragraph where excess value is introduced and the section about kernel offsets.
* fix and clarify section about kernel offsets
"Splitting" the blinding factor into *k1* and *k2* is unnecessarily confusing I think. The excess and the offset are really two arbitrary numbers without any mathematical relation to each other. I think I rephrased the section as well as I could without sacrificing any correctness for the sake of simplicity (which I think would be more confusing than helpful).
* do the same fixes for the Swedish version
* small fix regarding aggregation
Transactions are not aggregated by non-mining nodes as well. Removed the part about miners.
