Misc: Code cleanup & debug code changes
- Merge @daBrado's focus event debugging code. Thanks! - Use macro to reduce code redundancy in various functions. - Move focus event validation from ev_focus_out() to a separate function. - Add logic in ev_handle() to increase the chance of successful window name detection if compton is not reading window names normally (i.e. if there's no --shadow-exclude), when DEBUG_EVENTS is on.
