Make documentation more accessible

[salkinium]

Currently the Readme contains the whole documentation, which is fairly complete, but not super useful to access.

Wishlist:

• Have a proper website at lbuild.modm.io or readthedocs with overview, install instructions, development instructions etc.
• Split the current Readme documentation into smaller and searchable modules.
• Find a way to install the docs with pip install lbuild
• Manpages? or at least a better lbuild -h.

Find a way to install the docs with pip install lbuild

Once the documentation is available on https://lbuild.modm.io/ I don't think we need the documentation in a pip package. lbuild -h could then refer to the website.

For a start: What do you think about showing the current README on https://lbuild.modm.io/ and pointing to a (non-empty) ReadTheDocs there?

Yes, just currently working on too many things at once, hence opening this issue.
