Enable overnet

Description

Enables Overnet searches and filetransfers.

Functionality varies a lot, both the network itself and the implementation is basically in alpha testing, and furthermore the protocol, wich is proprietary, has not yet been completely reverse engineered. _Don't_ turn this on and leave home. Monitor it closely for a while.

_From #mldonkey on IRC: Overnet support is in need for a maintainer since last December (12/2002) ... as the protocol evolved since then (in part to block mldonkey) the Overnet support is almost not working /Pango_

_Overnet support in 2.5.3 seems to be problem-free (probably not at optimum performance, but download/upload do work), so I'd leave it enabled on a decent connection. /kernunnos_
