New in version 0.1:

- Added "search" functionality. It is now possible to search and locate
  specific events that match a Query. The next (or previous) matching
  event is displayed and highlighted, so is the timeline that contains
  the event. Searches can "wrap around" if desired.

- New import filter classes can be added to Zeitline even without
  having to recompile the whole software. It is sufficient to create
  a class that extends the abstract InputFilter class and copy that
  class to the "filters" directory. Zeitline will recoginze those classes
  at startup and make them available during import.

- Added a Linux syslog filter.

- Changed the InputFilter.init() method declaration to include
  a Component parameter. This allows filters to pop up windows to
  query data.

- Added a progress bar for the import process. It is now possible to
  cancel an import while it displays the progress bar.

- Makefile can now generate releases.

New in version 0.alpha:

- Fixed null pointer exception when choosing 'Clear selection' menu item
  when no timelines are in the project yet.

- Fixed error in the 'paste' functionality when performing a cut and then
  pasting the data back to the same parent event.

- Fixed key accelerators for menu and toolbar actions.
  NOTE: key bindings might be subject to change in the future.

- Removed icons from menus.
