Add option to specify per-file or per-group processors in wro.xml

[GoogleCodeExporter]

Right now, we have to have a global list of processors in wro.properties which 
is applied to all groups.

It would be nice to have extra attributes in wro.xml to specify per-file or 
per-group processors, for example:

<group name="all" preProcessors="cssImport" postProcessors="cssCompressor">
  ...
</group>

I'm interested in this because I have some already minimized files that I want 
to concatenate with the other files, but I don't want to process them in any 
way otherwise.

I understand your use-case and it seems useful feature. The only concern is 
that this change requires quite a lot of work and probably won't be available 
very soon. If you are willing to contribute, I will gladly accept your pull 
request and provide you with any help if required.

I'm really interested by this feature because it's common to apply specific 
strategies regarding the files or groups. 

Hope this feature will come soon ;)
