focus username field of login form by default

Since 3.0.0 we're not preserving Administrator in username field on
logout. So it makes sense to focus first field which is now empty and
requires user input.

[ale] added api to batch logger config compilations

It's now possible to wrap ale (re)configurations with call to
ale:with_configuration_batching/1. Within "body" of that call all ale
compilation is delayed and at the end of that call all loggers are
recompiled.

Using that API allows setup of complex ale log topologies without
overhead of recompilation on every call to ale:add_sink and
ale:set_loglevel.

improved startup speed by using ale:with_compilation_batching

Which eliminates about 4 seconds from startup time on my box by
batching logging configuration compilations.
