This is redundant and introduces confusion especially when the argument has a name and value (e.g. `-plugin plugin_name,arg=3D"argname=3Dargvalue"`= ). This allows passing plugin arguments directly e.g: `-plugin plugin_name,argname=3Dargvalue` For now, passing arguments through "arg=3D" is still supports but outputs a deprecation warning. Also, this commit makes boolean arguments passed to plugins in the `argname=3Don|off` form instead of the deprecated short-boolean form.
