May 2011:
- added contributions by Onno Zweers:
  - synctool-diff patches
  - tasks/functions shell scripting library
  - a script that cleans dirs but also has whitelisting capability
- checksum performance gain when there is no match
- bugfix for running a single task
- options -1, --single, --diff, --ref can be given multiple times on a
  single command-line to handle multiple files
- 'synctool-config --nodename' displays my nodename
  Which comes in handy when scripting .post scripts
- dumped synctool_core for synctool_overlay, which has much cleaner code
  and supports having multiple overlay dirs, which are merged together
  in memory
- .post scripts for directories are now run _in_ that directory rather than
  in the parent dir. So the current working dir has changed
- .post scripts for directories are run at the very end after making changes
  to all files. This shouldn't break anything unless you have (weird)
  dependancies over multiple directories with .post scripts
- fixed possible bug for on_update where quotation was lost for the command
- added new config parameters for overlaydir, deletedir, tasksdir, scriptdir
- added new config parameter require_extension (default: yes)
- added new config parameter backup_copies (default: yes)

- full_path can be set from cmdline using -F and/or --fullpath
- $masterdir can be used in the config file to reference parameter 'masterdir'
- synctool-ssh/dsh now has option '-o' for passing additional options to ssh
- possible bugfix for symlink mode on platforms where it matters

- upload creates the repository (sub)directory if needed
