Implement inhibit_idle command

This implements the following command to set/unset a user idle
inhibitor for a view:
`inhibit_idle focus|fullscreen|open|none|visible`

The modes are as follows:
- focus: inhibited when the view is focused by any seat
- fullscreen: inhibited when the view is fullscreen (or a descendant of
  a fullscreen container) and is visible on any output
- open: inhibited until the view is closed or the inhibitor is unset or
  changed
- none: unsets any user set idle inhibitors for the view
- visible: inhibited when the view is visible on any output

This should have no effect on idle inhibitors set by the applications
themselves and those should still work as intended.

Since this operates on the view in the handler context, it is possible
to set it on the currently focused view, on any existing view with
criteria, or for any future view with for_window.

+*inhibit_idle* focus|fullscreen|open|none|visible
+        Set/unset an idle inhibitor for the view. _focus_ will inhibit idle when
+        the view is focused by any seat. _fullscreen_ will inhibit idle when the
+        view is fullscreen (or a descendant of a fullscreen container) and is
+        visible. _open_ will inhibit idle until the view is closed (or the
+        inhibitor is unset/changed). _visible_ will inhibit idle when the view is
+        visible on any output. _none_ will remove any existing idle inhibitor for
+        the view.
+
+        This can also be used with criteria to set an idle inhibitor for any
+        existing view or with _for_window_ to set idle inhibitors for future views.
