741c6f274e Add support for @include and @includedir 
These are less confusing than #include and #includedir when the
hash character is also the comment character.

This commit also adds real parsing of include directives as opposed
to the pure lexer approach used previously.  As a result, it is now
possible to include files with spaces by either using a double-quoted
string or escaping the space characters with a backslash.

c039a99c10 plugins/python/sudo_module: add sudo.LogHandler 
so python log system can be used with sudo logsystem.

If that is not the intent, it can be overridden explicitly.
