Check usernames in the database as case insensitive, they are still stored case sensitive. Bug fix for oc-422 and oc-1514

LDAP: implement getHome() function, use either username (default) or specify an LDAP attribute value to use

Remove sharing notice in users settings - The default is now share with anyone, groups only sharing is now a setting in the admin page

LDAP: transliterate other latin characters to ASCII when creating owncloud names. Already created usernames are not being affected.

remove files_imageviewer and files_texteditor from blacklist so they can be activated in a multi apps environment

add length to text columns or newer mysql will produce columns too wide

setbackgroundjobsmode.php got lost somewhere - switched call to use the perferred OC.AppConfig.setValue() instead
