Before this commit, params in paths had to be be between slashes and
comprise the entirety of the contents between those slashes (eg:
`/books/{{id}}/{{name}}`)
This is unnecessarily restrictive. This commit removes this restriction,
which allows for paths such as:
- `/books/{{id}}-{{name}}`
- `#books&id={{id}}&name={{name}}`
among others
closes#858
In most cases, we just want Component<any, Env>. But since it was so
annoying to have always the type Env, we actually used
Component<any,any> everywhere.
With this commit, the generic types have a default (and their order is
swapped), so we can simply use Component in most cases, and
Component<Props> when we want to type the props.
It now takes two arguments: parent (optional, only for non-root
components) and props (optional). In the case of the root component,
the env is taken from the config (config.defaultEnv). If it doesn't
exists, the default env is created on the fly.
