news/sabnzbdplus: Port cleanup

• Better define which versions of python sabnzbd can actually run with

• Remove "+" sign from SUB_LIST

• Modernize OPTION RUN_DEPENDS

• Do not set PATH in rc script

• Make patch and reinplace more logical by not replacing %%PREFIX%% with

%%DATADIR%%

• Remove creation of PREFIX/sabnzbd (sabznzbd's config directory) from

install as it is already handled in start_precmd routine

• Replace INSTALL_DATA with INSTALL_MAN for installing PORTDOCS

• Hand off maintainership
