Issue #52: Added 'd' hotkey for the ztree-dir to open dired.
Now in ztree-dir mode hitting 'd' will open a dired
for the directory the point is standing on;
otherwise the dired will be open for the parent directory.

* To toggle open/closed state of the subtree of the current directory, hit the
`x` key.
* To visit a file, press `Space` key.
* To open file in other window, use `RET` key.
+* To open `Dired` with the directory the point is currently on, use the `d`
key.
### Customizations
Set the `ztree-dir-move-focus` variable to `t` in order to move focus to the
other window when the `RET` key is pressed; the default behavior is to keep
focus in `ztree-dir` window.
