Changes are:
* Don't compile in the background anymore, only via the `zimfw` tool
after actions where scripts can change (build, install, update)
* Move compilation of the completion dumpfile to the completion module:
9386a76eac/init.zsh (L10-L11)
* Don't compile users startup scripts anymore (.zshenv, .zshrc, etc.)
* Make output of `zimfw init` friendlier for the terminal startup
screen when called without `-q`.

Regarding not compiling users startup scripts anymore, I'm choosing to
only compile the modules' scripts at least for the reason that compile
won't happen so ofter anymore -- it will only happen when the user calls
the `zimfw` build, install or update actions. So it makes more sense to
only compile the files that `zimfw` has control over changes...
