Bloom / HDR shaders

[GoogleCodeExporter]

I think bloom/hdr shaders (optional, of course) could further improve the 
graphics and it's very easy to implement (there's a nice compositor framework 
in Ogre and bloom/hdr compositors in samples).

The problem is there doesn't seem to be a way to render mygui after the 
compositor (correct me if i'm wrong). It has a quite funny effect, it makes the 
GUI partly transparent with a blurred version of the render behind it. Looks 
cool :)

Solution could be to remove the compositor when GUI is opened, and show it 
again when GUI is closed. (setCompositorActive)

Another solution: render mygui to a seperate, transparent viewport that is on 
top of the normal viewport.

Btw, if the compositor is already in, one could add Motion Blur too.

Using Dark Sylinc's Bloom implementation, the gui issue seems to have gone.

Compositors can now be enabled via config file. GUI exists too, but it doesn't 
do anything atm.

What's still missing now:

- Motion blur implementation that 1. actually works and 2. only blurs moving 
objects.
- When using the compositors, some overlays like dot on the minimap and gauge 
needles are gone.

overlay needles and player pos dot issue is gone. It was incorrect to use a 
different render queue group for them. Instead, this has to be done with z 
orders.

I'm setting this to solved for now, as this issue was only about bloom / hdr. 
Motion blur will be addressed after 1.1 release, then this issue can either be 
re-opened or we create a new.
