Comment 3 for bug 1668492

Notes for testing:

Theme settings

* site theme

a site admin can change the site theme under
 Administration
 Configure site
 Site settings
 Theme
This is the theme shown when there is no other personal or institution theme set

* browsing theme

The theme that a user sees in its own portfolio
If the user is a member of an institution, the browsing theme by default is the institution theme
If the user is a member of more than one institution or the $cfg->sitethemeprefs is set to true in the config.php file
this theme can be changed in
 the top right menu
 Settings
 Theme

If the site or institution admin changes the theme of the institution, the user will see this change in the next login
If the user shares a view with other users, they will not see the browsing theme of the user,
instead they will see the views with:
 the view theme, if it has one
 if not, the owner institution theme
 if the view owner is not in an institution, the site theme

* view theme

If this is enabled in the site by the site admin
 Administration
 Configure site
 User settings
 User can choose page themes

then when editing a view a user can set a theme for that view only
