DB/Errors

Browse Source 
* improve db error handling
 * web view should always result in an user friendly error if the db connection is missing or erronous
 * cli use should never fatal if the db connection is erronous. How are you going to fix it, d'uh.
 * if some CLISetup script requires a db connection check it individually
