Patch for zoom in/out the userinfo image

[gallows]

Hi,
I wrote this little patch, hope you find it useful.
I basically added an EventBox? on the UserInfoTab? so to handle the mouse scroll signals in order to increase and decrease image size.

List of modifications:
userinfo.py:
Added three functions (on class UserInfo?).

• OnScrollEvent() - it manages to handle the signal of the EventBox? I added, by calling one of the following two functions:
  
• MakeZoomIn()
  
• MakeZoomOut()
  

Furthermore I added the following variables (always in the same class):

• self.image_pixbuf - for the zoom (otherwise the image quality is compromised when zooming), but also for the image saving (little change already realized).
  
• self.zoom_factor - the zoom factor. This is not necessary, but anyway preferable than a "magic number".
  
• self.actual_zoom - records the current value of the zoom.
  

I had to call the garbage collector on every zoom because a strange GC behaviour [1]

glade2py.py:
Added the support for a GtkEventBox?.

nicotine.glade:
I just added an EventBox? (between viewport2 and image) to which i connected (on scroll signal) the function OnScrollEvent()
(I used glade-2)
