* Add documentation
* Use modern coding standards
* Move URL creation out of `apply_filters()` call to improve readability
* Escape output of `bp_group_creation_previous_link()` with `esc_url()`
This change improves the readibility of the code used to generate the URL to the previous group creation step, and also ensures the URL is properly escaped when output (in the event the return value is intercepted with otherwise unpredictable results.)</pre>
