Inner classes

[KwangYul Seo]

Hi,

I guess the following classes should be static inner classes.

- FtpletEntry (in FtpletContainer)
- TableEntry (in FtpDirectoryTableModel)
- TableEntry (in FtpFileTableModel)
- Entry (in IPRestrictorTable)

These classes do not use its embedded reference to the object which created
it.
This reference makes the instances of the class larger, and may keep the
reference to the creator object alive longer than necessary.

Thanks,
