[Opensim-dev] Effect of entries in [Modules] in OpenSim.exe .ini files

[Justin Clark-Casey]

This is not ideal since classes are being added which will never be used.  However, if these classes are never 
instantiated, the effect on memory usage will be minimal.

I don't know exactly how the [Modules] config parameters are working, but it would make much more sense for 
OpenSimulator to decide which modules are enabled rather than relying on the modules to detect this for themselves.  The 
latter approach is potentially inconsistent and vulnerable to bugs in modules.
