[FR] Add DHCP and more network features

[J013k]

Currently wLaunchELF can only supports static address:

Is there any chance to also add DHCP?

Is there a way for wLe to enter shared folder without e.g. Rad Host Client 1.8a? Something like in OPL, where games can be listed but instead of that I can use for example "wLe" share not "PS2SMB"?
