+ non-www redirect nginx script (with todo)

+ domain_name & refactored nginx variables for resolve connect of www-domain logic and redirect to or from
* some installs have error after login to non-privileged user with starship $-symbol - correct escaped function for that
+ use separate domain for pma nginx config based on new domain_name variable (defined in nginx vars file)
* update database example vars (use inventory dir path and bz2 by default)
