Fixing a regression bug

When remove the ~ (tilde) syntax from package.json, it was not replaced with thew new ^ syntax.
Version 0.2.1 therefore was using 0.1.3 of each-async, while Version 1.0 regressed to 0.1.0 of each-async.

- Adds ^ syntax to each-async
- Sets minimum each-async to 0.1.3

Further; UTF8 prior to node@0.10.29 would incorrectly handle utf8 conversion from non-compatible sources (like a binary image).
This will end up causing all new hashes for all new files.
