stop calling validate() in newReader/Writer()

By not calling validate(), we can add
non-invasive features which will be simply ignored when user-code
is compiled against an old version. That way, we can often
avoid a minor version-bump.

The user can call validate() himself if he prefers that behavior.

CharReader/Builder

I guess we should but the patch-level version. We will set the version properly soon...

1.2.0

 `operator=()` (which already performed a deep-copy) now includes comments. This change is probably harmless in all practical cases. But just in case, we bump the minor version.

Address open-source-parsers#47.
