[Qgis-developer] Wrote a RGB Composition plugin

[Mauricio]

For those who always wanted to make rgb compositions without loading the data 
into grass, here it's your plugin. It's nothing great but i think it works.
Can anyone be kind enough to test it? It's in the default repository and it 
requires the python-gdal to be installed in the system. (I'd really like to 
know if there is an easy way to install it on windows)
Thanks to Frank for the idea of using gdal directly.
