WarpIN and bootloader istaller integration

[21:19:31] _yoda: I was thinking about creating the Installer as a GUI app. I have never really 
created such a thing before - but most of current code should work in Sibyl too
[21:26:54] valeriusN: _yoda GUI installer can be made as optional part, but it is not really 
needed. I think it must have a minimal UI. It must work as a standalone installer with user 
interface. It would be desirable if will have a DOS or win32 version, as several windows users 
asked me for an installer; it can be useful for other platforms users too, so they must also 
have a (portable) installer version. 
[21:26:58] valeriusN: Also, we would like to have an installer version as a DLL callable from 
our version of warpin, for integration into osFree installer
