Create a My Settings page, now linked when clicking a User
Create backend preferences form for setting locale
Dropdown options now support an image or icon in their options
Moved hard-coded text in "backend" and "system" to the language files
(English and Dutch). Affected pages: administrator management,
administrator group management, system updates, system settings, email
settings. Also made some strings more generic for general use (like
"Saving...." instead of "Saving administrator account...")
