    ls: Don't close it after file opening when opened from the project tree
    
    Currently when choosing a file in a folder browser opened from the
    project tree menu, the folder browser is closed.
    
    But this behavior is inconvenient when someone wants to use the folder
    browser as a persistent and pane-able view of a folder.
    
    So this commit changes this behavior to let the folder browser opened
    after opening a file. It is still possible to use it as a vim-like
    directory listing, by using the "Switch to Folder" item in the right
    click menu in an editor view.
