#1191 Fix code using nextPut[All]: to use << or write:

Originally at 2015-06-13T19:09:56Z by Herbert Vojčík The stream operations `nextPut:` and `nextPutAll:` are in fact low-level operations. The high level operation to put an object into a stream (which then translates to to low-level ones) is either `write:` or `<<` (they both do the same). Code in Amber core that uses `nextPut:` / `nextPutAll:` as regular way to put data on to a stream should be changed to use the high level operations instead. <bountysource-plugin> --- Want to back this issue? **[Post a bounty on it!](https://www.bountysource.com/issues/21879646-fix-code-using-nextput-all-to-use-or-write?utm_campaign=plugin&utm_content=tracker%2F79201&utm_medium=issues&utm_source=github)** We accept bounties via [Bountysource](https://www.bountysource.com/?utm_campaign=plugin&utm_content=tracker%2F79201&utm_medium=issues&utm_source=github). </bountysource-plugin>
