Ticket #3045: change behavior of the 'Right' key

...in 'Directory hotlist' and 'Active VFS directories' windows.

Previously, the 'Right' key was used for:
1) move to the selected directory in the 'Directory hotlist' window;
2) enter into the selected group in the 'Directory hotlist' window;
3) move to the selected VFS in the 'Active VFS directories' window.

1) and 2) cases look as inconsistent bevavior because only two these
dialogs are closed after 'Right' key pressing.

Now 'Right' key is used only for 2) case and ignored in 1) and 2) cases.
