[Vm-dev] FT2Plugin stops working with latest version

I'm coming back with this issue (yep... no time last couple of weeks, but this one is a lot better :) 
I still can not compile FT2Plugin with the last changes, adding: 

	#bytesPerWord 			#generateBytesPerWord:on:indent:
	#baseHeaderSize			#generateBaseHeaderSize:on:indent:


you know, real problem is that #generateBytesPerWord:on:indent: generates a plain "BytesPerWord"... but BytesPerWord is not defined anywhere... so I assume there is something I'm missing, but I don't know why. 

In other things, I'm determined to produce a beta release this week. As far as I know, I just need to solve some minor issues: 

1) this FT2Plugin issue
2) externalize OSProcess (yes... I don´t like to have it as an internal plugin)
3) a stupid issue with localization strings (just used on open images)

and I don't think anything else :)
so... if you help me with this issue... you will make me very happy :D
