Create site:

- Gives a nice error for duplicate shortNames
- service returns "error.duplicateShortName" as the message so a proper error message can be displayed to the client.

Delete site
- Icons for each site (a small typo had gone into the css in the previous commit)
- Handles a failed delete better (i.e. because of lacking permissions)

Full preview & Preview
- Does only display their page navigation controls if more than 1 page exists
- Does not display an error message if an invalid page is given (displays the last or first instead)

Preview
- Displays its controls above the preview instead of below

Full Preview
- If its an web image (jpeg, png, gif) it displays the actual image instead of a imgpreview

Dashlets
- All dashlets use Camel Case in their short name
- New shortName for Docsummary: Recently Modified Files
