 * Update look and feel settings

 * Updates the look and feel settings for the site or for a single space.

Note, if a theme is selected for a space, the space look and feel settings

are provided by the theme and cannot be overridden.

**[Permissions](https://confluence.atlassian.com/x/_AozKw) required**:

'Admin' permission for the space.
