Update NEWS and RELEASE-NOTES
emaint: Assign all module __init__.py's __doc__ to a variable intsead

Due to distutils-r1 eclass optimization level, __doc__ strings are removed, breaking the
plugin system's use of __doc__ for it's module description(s).
This causes tracebacks when trying to run emaint.
