Moved PermissionManager creation out of the Scene constructor and instead a PermissionManager is passed to the constructor as a param. So that we could create and use custom permissionsManagers.
Added AllowMovement property to ScenePresence which can be used to stop movement of avatars (for example in a custom region that wanted avatars always in one place).
Added PermissionManager call when copying objects, although currently the call will always return true so that it allows copying in places like Wright Plaza.
A few other changes/fixes.
Note this has lead to a big flat project, but I think a lot of the files we most likely don't even use any longer. And others belong in other projects/namespaces anyway.
* Introduced ModuleLoader.PickupModules that currently picks up IRegionModule:s from /bin
* Made LogBase thread-safe (or at least not thread-ignorant)
* Ignored some genned files
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)
Some work on the asset cache, can people please test this. including on one of the public systems so we can see if it causes problems with multiple users.
