'factory' and 'sysupgrade' did not make much sense. A discussion

So I decided to use '.bin' for normal bin-headers and '.noheader.bin'
for the trx-v2 image.
I fixed the wiki accordingly.

Boots on WGT643U, includes ethernet support, but doesn't do much otherwise.
Thanks to Michael Buesch for his SSB (Sonics SiliconBackplane) work
and Vladdy for some fixes and porting to 2.6.19.
