Alpha transition flush publish 191

let me know if you would prefer this be a seperate function
```
badgeos_register_post_types();
badgeos_register_achievement_type_cpt();
flush_rewrite_rules();
```
Ie
```
function badgeos_flush_rewrite_rules() {
    badgeos_register_post_types();
    badgeos_register_achievement_type_cpt();
    flush_rewrite_rules();
}
```
