Woadaptor

Hi,

finally I made it, integrating all my work on the WOAdaptor into Wonder.

Most important changes:
- bug fixes (many of them in IIS version, raising it onto the same quality level as the apache version)
- supports streaming downloads with unset content-length
- improved make settings for IIS, getting it compiled using MINGW for 32 bit and 64 bit IIS - installation docu extended for IIS 7.5 / Windows Server 2008
- CGI adaptor does compile well using MINGW 32bit and 64bit, too
- optional reintegration of refuseNewSessions attribute (new compile flag in make.config)

I merged my changes into the new Apache 2.4 subfolder, too

I guess you are unsure how to deal with these changes, as it might take quite some work to do a review - so I am aware you will be reluctant taking it. 

Regards, Markus
