Problem with custom httpAdminRoot

When httpAdminRoot is set to a custom value in the settings.js file, the UI is unable to retrieve the list of sensors, in the javascript console there is a 404 error.
Changing line 21 in file 98-ds18b20.html from

``` javascript
$.getJSON('/sensors/1wire/',function(data) {
```

to

``` javascript
$.getJSON('sensors/1wire/',function(data) {
```

will solve the issue.
