Web client : change "Image type" setting

[medvejonok]

Hello there,

I've been trying to find a way of hacking a default setting for how files are displayed in the web client when inside a folder. 

By default the "Image type" setting is set to "Primary". I would like to make it "List" for all folders.

I've had a look at the API, the SQlite database, the config files, and the console behaviour when changing the setting manually but have not yet found a solution.

How could I apply this change wholesale to my entire database of folders ?

Thanks for any pointers !
