pip install cleanup about bqt

[hannesdelbeke]

believe this is solved now. pip install wont auto add to startup anymore. instead bqt can now be loaded as an addon. which handles startup. and prevents poluting of vanilla blender install folder

[hannesdelbeke]

noticed the setup.py still contains ref too dist/bqt_startup.py

• remove this
• make local package and test install
• release github package and test pypi build action, now that the secrets are hooked up

adding ref to blender pip. https://github.com/hannesdelbeke/blender_pip
since we handle clean blender pip installs there

[hannesdelbeke]

• removed dist/bqt_startup.py from setup.py
• tested pip install
• made first release https://github.com/techartorg/bqt/releases/tag/1.0.0
• action to auto build and upload pypi package worked
• noticed bqt_demo is also included in the pip install? not sure if we want that. likely cause we use setuptools.find_packages()

[hannesdelbeke]

bqt demo has been removed from package
