number of hash marks, clearly specify example settings and what the
defaults are set to.

Thanks to Ian Beckwith <ianb@erislabs.net> for the patch.

updated the example.maildir to include this option, as well as detail the missing desid_file, destport

The modelines added match the emacs lines already present and also set
the filetype to sh (just like the emacs lines).

Previously, there were many indentation styles in use: Real tabs, 2, 3
or 4 spaces, mixing these within the same file, function or even within
a single line.

This commit changes all bash scripts in the handlers, src and lib dirs
to use consistent indentation: three spaces are now used everywhere.
Other files (e.g. Makefiles) are left untouched.

Additionally, this commit removes all trailing whitespace.

... and populate it with autotools/build files.
This is of course intended to make life easier for people using git-svn.
