LyteCFG: Lighttpd configuration GUI

Screenshots

This shows the tree view, which allows any option (including ones that LyteCFG does not know about) to be configured.

These shows 2 of the more specific configuration tabs, and any changes here are kept in sync with the tree view. These are intended to handle the more common-case configuration, and the plan is/was to also include panels that give pre-packaged configurations.
