[Qt-creator] Extend Qt-creator to recognize source file extension .xc

[André Hartmann]

Hi Leandro,

thanks for your answer and pointing me to the XML file. I just tested 
this with a 2.0.1 creator and it seems to work. I will try to compile 
the current Beta next time, but I had some trouble with it last (maybe 
Qt / QtCreator version problems).

To be honest, me and my colleague both don't really know where the 
extension .xc comes from, maybe one of the first examples we got used 
this convention and we never changed it :)

But for us the file extension is an easy way to map the files to the 
appropriate compiler (S12X CPU or XGate coprocessor) in our Makefile.

The funny thing is, that Freescale itself uses the extension .cxgate in 
examples for their Codewarrior compiler (we use http://cosmic-software.com)

If the XML file wouldn't be embedded, one could easily adopt it without 
recompiling. Is it worth to add this on the wishlist in your bug tracker?

Anyway, thanks for your time,

Bye Andre
