Some work on Module loading/management.

Some more modules templates classes (hoping that someone will pick some of these and work on implementing them).
Early version of the "Dynamic Texture Module", although currently there are no render modules included (so not really functional without them). 
Added osSetDynamicTextureURL script function, for attaching a dynamic texture to a prim. 
Some work on the console command handling. Added "change-region <regionname>" and "exit-region" so that after the use of change-region, the commands entered will apply to that region only. Then use exit-region to return to the top level (so commands then function as they did before and either apply to all regions or to the first region) (Note: this hasn't been tested very much)
