Implement a simple way to debug (println) in re-frisk

[flexsurfer]

For example
(dispatch [:re-frisk/debug [:test value]]) -> :app-db -> :re-frisk/debug -> :test
or
(dispatch [:re-frisk/log [:test value]])-> :app-db -> :re-frisk/log -> time :test

this must go not in the db but in the events section, like debug event , for example when you want to print some complex data , its really hard to read it in console, in re-frisk it would be more convinient
