- Mako is now a core dependency
- therefore no more 'email' extra
- add `get_install_handler()` method for app handler
- add `render_mako_template()` method for app handler
- add `resource_path()` method for app handler
- install handler thus far can:
- confirm db connection
- make appdir plus config/scripts:
- wutta.conf
- web.conf
- upgrade.sh
- upgrade db schema to create tables
- from there web app can run, create admin user
- quick start docs now describe "generated code" option
i think it only makes sense to have an "opinion" for command line
interface in this project, and we probably need more `wutta`
subcommands too but we'll see.
main motivation for this currently is to allow poser apps to define
their own CLI, in particular e.g. `poser install`
