Allow to configure the action when touching a file in browse mode

Currently, when browsing files the are 3 possible behaviours:

• touch the image which select the file
• touch the 3 vertical dots which show a mini-menu available actions on the file
• touch the filename which directly plays the file.

That last behaviour can often be problematic because it deletes the current queue and play the file.

One idea to improve that situation would be to have a setting to choose what is the default action when clicking on a file, and the options would be: open the mini-menu, append, append next (cf #2141), play, etc.
