Adding split/split' to Data.List, and redefining words/lines
with it; also, adding replace/replaceBy

Just wanted to chime in with some historical perspective (no doubt
with a few gaping holes, so feel free to correct me).
There's a brief summary on the wiki of the prior discussions:
These are the two previous threads:
Some interesting points:
- the lines/words analogy to split/split':
Which reinforces Gwern's point that the library should have both.
- Perl, Python, and Ruby do not agree on split semantics:
- there seems to be some desire for functions splitBy and tokens,
which haven't been mentioned (yet) in this thread, I think.
And finally my opinion:
> split 'a' "aXaXaXa" == ["","X","X","X",""]
> split' 'a' "aXaXaXa" == ["","X","X","X"]
I prefer the ByteString split (i.e. I prefer separator semantics over
terminator), also because it's invertible. Some more support:
