11625	Start using different hashes instead of timestamp for loading resources (via getUrl)	Wiktor Walc	Artur Delura	"Using timestamp to mark unique builds worked fine in the past where we released packages once per ~month.

Now, when lots of users try different builds, overwriting the same location and then scratching their heads why something does not work, we need to do something different. See for example http://ckeditor.com/forums/CKEditor/Bug-with-custom-builder-and-language-selection, there were more issues reported like this.

My suggestion is to go with assigning a `random` hash when creating a build. There is no sense in calculating the hash based on the list of enabled plugins (and their versions, btw. we do not have this information in case of using command line builder), languages etc. Using a hash that is complex enough will do the trick.

Using 6-characters long hash that consists of small letters + numbers, gives ~1 838 265 625 (`35^6`) combinations if I counted correctly (1.8 billion)."	New Feature	review	Normal		General
