Add full lando - with extra ahoy tooling + optionally extra 'ahoy-like' lando tooling

[silverham]

Allow lando to be used, so we can have multiples of the same project with no conflict (.env has to be committed) and other lando goodies.

See PR for full lando: #82

Or trimmed version (no 'ahoy-like' lando tooling): #83

Feel free to make changes, test etc.
