Title: Restricted chars in space URLs and updated the description text

The following are the changes I've made.
1. Space URL chars must be lowercase, digits or underscore: reimplemented it using the RegexValidator class of Django.
2. Updated text displayed when a space is being added to tell user that Description of a space is publicly visible.
