Merge #26 

26: Fix vectored I/O r=jethrogb a=parasyte

This is a large PR because I recreated all patches from #18. Contains the following fixes:

- `ioVec` does not depend on `feature="collections"`
- Fix `impl Read for Take`; only `read_to_end` requires `feature="collections"`
- Fix some whitespace consistency issues

Closes #19
