[enh, usability] Remember view settings per directory

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv: Gecko/20061201 Firefox/ (Ubuntu-feisty) Build Identifier: Currently it is not possible to make a particular directory to remember view settings. For example if my default view settings are View as compact list but I want some directories to display files as icons I cannot do it. Could be quite useful for dirs with images and so on. Reproducible: Always Steps to Reproduce: 1. Open Thunar 2. Enter any directory and change view 3. Leave the directory and see that all other directories have the new view settings Actual Results: All other directories have the new view settings Expected Results: There should be an option to have settings are changed only for this particular directory while other dirs retain the default settings set in the Preferences.
