Intellij friendly error message
Ignore resource directories when trying to loadMessages in MessagesPlugin, otherwise app don't start if there's a matching directory
remove unnecessary exec ctx prep from Iteratee.flatMap

commit 2b276d24 implemented the lines:
```
case Step.Done(a, Input.Empty) => executeIteratee(f(a))(ec /* still on same thread; let executeIteratee do preparation */ )
case Step.Done(a, e) => executeIteratee(f(a))(ec.prepare /* still on same thread; let executeIteratee do preparation */ ).pureFlatFold {
```
However, the `ec.prepare` is incongruous with the adjacent comment, and the preparation is definitely not required as the preparation is indeed handled by `executeIteratee`.

Methods to serialize JSON with non-ascii characters escaped

In some situations (such as JSONP with strings containing U+2028 or U+2029) it is useful
to escape all non-ascii characters in the generated JSON string.
This provides Json.asciiStringify and JsValue.toAscii to accomodate this.
