Fix #127 Ant build and package.properties improvements (#129)

- **Class-Path** has been added to the `MANIFEST.MF` file.
- No other archive is created when generating the `build.xml` file.

In addition to these two fixes, the management of the package.properties
file has been revised to correct the following problems:
- When deserializing (ie: reading the package.properties file), if any
resources are missing or modified, a message will be logged and the file
marked as modified (ie: isDirty() returns true).
- When saving if there are any pending changes (ie: if you used the text
editor or when opening missing files are displayed) then the text editor
will be reloaded.
- A specific listener for refreshing the widget (ie:
ContainerCheckedTreeViewer) has been implemented.
- All listeners loaded on initialization are now removed during
dispose().
- Hidden files and/or folders (ie: starting with dot) management is now
supported.
- It is now possible to include a folder in the selection if it is empty
(ie: no visible members).
