Refactoring

This is a big commit. Because this project is in an early state
it does not make sense to split up this commit in several smaller
commits.

- Changed pkgbuild_template.rb to an erb file. With something like
  'File.expand_path('../../../i18n', __FILE__)' it can be loaded
  without problems.
- Removed dialects from language file-names (it didn't work).
- Removed TODO file (http://redmine.sevenbyte.org/projects/gempac/wiki/TODO)
- Put the i18n folder on the correct position.
- The query command works now.
- Removed some debugging things.
