Add queries to If actions

Browse source 
This allows the If action to run queries against a client other than
the target of the actions being run, for example to check state on
the focused window while performing actions on another window during
focus cycling.

The syntax looks like

<action name="If">
  <query target="default">
    <title>FooBar</title>
    <maximized>yes</maximized>
  </query>
  <query target="focus">
    <desktop>3</desktop>
  </query>
  <then>
   <action name="NextDesktop"/>
  </then>
</action>

The above checks the client window that the actions will run on to
verify that its title is "FooBar" and that it is maximized. If that
is true, it also checks that the currently focused client window is
on desktop 3. If that is true also, then it runs the NextDesktop
action.

The target="" option can be set to "default" which uses the client
window that the actions will run on, or it can be "focus" which uses
the client window that is currently focused.

The <query> tag is optional, and the conditions inside the query can
be placed directly inside the If <action> tag, as they were before
this change. In that case, a default <query> tag is assumed with
target="default" which matches the previous behaviour.

Multiple <query> tags can be present, and they must all be true in
order to run the actions in <then>. If any one is false, the actions
in <else> will be run instead.
