* Added "File Asset Client" to OpenSim Asset Server-types.

* You can replace "grid" as the asset system with "file" to save and load all your assets from a directory on your hard disk. Files are serialised to XML and saved in the format "/<dir>/0x/0x/0x/0000-0000-000000-0000-0000.xml"
* Directory <dir> is sharing the Asset Server URL path, use a normal path here instead (ie C:\xyz or /var/assets/). 
* This probably wont work well in grid mode unless every sim has access to the same directory. This is mostly intended for standalone usage where quick and convenient access to assets is required.
