[Owncloud] Bookmarks optional description or DB structure

[Arthur Schiwon]

Hey,

those who use this app with MySQL maybe want to change the field "description" 
in the bookmarks-Table to notnull = false, in order to store bookmarks without 
typing a description. As until now it was set to true, making it a required 
field. 

Sqlite is not affected. 


My MySQL command to change this structure:
ALTER TABLE  `bookmarks` CHANGE  `description`  `description` VARCHAR( 255 )  
NULL DEFAULT  ' '

Cheers
Arthur
