Added meditation info

Added a page for [drg_link link=/retreat/practices/walking/ title=”go to page for Walking meditation”]walking meditation[/drg_link].

Retreat dates: October will be 10 days, and in November there will be a 21-day retreat (for advanced meditators) as an extension of the 10-day — until 30th.

Dress Code page updated

The Dress Code page has been updated, hopefully now a little better organised and more nicely worded. And with a reference to Words of The Buddha regarding white clothes. Enjoy!
