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.
Closes#306
Before this rev., default values weren't taken into account when
validating props whenever a component was updated. Moreover, there
was no test attesting that props were validated at update.
it is not useful to do it in the component directive, especially since
it is done in the constructor, and the default props are not applied.
closes#379
Before this commit, hashchanges were not taken into account by the
router, if used in history mode.
Also, it's stupid, but i ran prettier on the codebase
