Version upped

fix visibility changes in chat dialog

lazy load embeddings, storage and model

This should fix an immediate problem with the sqlite db initializing
slowly, but the underlying problem has to be identified.

added button to reset the conversation

This is needed to start conversing on a new topic

use a cut-off point when considering similar documents

added helper to quickly check the available models

show similarity scores in CLI

parse answers as markdown

refactoring to make models selectable

This makes it much easier to add new models. Models can now be selected
via the configuration

Use overlapping chunks, prepare for new models

removed K-D Tree vector storage

Since this implementation does not have any advantages over the SQLite
storage it makes no sense to keep it. Other storage backends might come
though at a later time

avoid empty chunks

fix URL when installed in root dir

added float option

fix focus and z-index behavior

do not use title on chatbutton element

It's influencing the dialog. A separate attribute that then sets the
title on the start button only makes more sense.

adjustment for renamed function in sqlite plugin

allow to restrict access to certain users and groups

add optional conversation logging

This might be useful to debug and monitor the real world usage of the
bot and analyze abuse.

optionally use text renderer for chunking

added a few todos

do not use very small pages as source

These are usually not helpful as context, but may throw off the nearest
neighbor search.

added usage statistics
