Once before installing/updating to prepare _zmodule_xargs, and once
after modules are updated, so functions and scripts can be found inside

are empty at first.
to autoloads the functions and sources the scripts, instead of executing
zimfw during startup, and having it always figuring out what do to on
the fly.
This takes out the worry about zimfw interfering with the startup time,
and allows room to add more features to it. So, zstyle was replaced by a
custom zmodule function to define the modules, with the extra ability of
allowing users to set custom fpath paths, autoloaded functions and
sourced scripts per module.
