Indication for read-only folders

[humdinger]

This hrev46250.

Add an overlay of e.g. a small pad-lock to indicate read-only folders. Choose the upper or lower right side of the icon so it won't collide with the already existing overlay for special folders (apps, preferences, develop etc.).

Having (another) overlay icon may become a bit intrusive, esp. when all subfolders in a directory gets one. Instead, a tinted folder icon and window background may be a better idea.
Query windows are grey tinted, virtual folder could be blue tainted, read-only folders could be orange tinted. (IMO orange tinted works better than e.g. red. It's also a "Haiku colour".)

I created a padlock overlay for this:

Applied with hrev46382.

A folder with the padlock overlay

When you're in a read-only location, the padlock icon could be placed beside the folder icon at the top right in the menu bar of the Tracker window. No need to add the icon to every single item in that read-only location.
