Ginn should detect conflicting wishes

[Gustavo Luiz Duarte]

Ginn should detect and warn the user when there are conflicting wishes.
For example, the current wishes.xml on repository contains 2 finger drag for scrolling globally and 2 finger drag for page up/down on firefox. If the user drags 2 fingers on device while using firefox both actions are triggered. It confuses a lot the user.

the fix committed on related branch in this new code
just the first one run and the other not effect on gesture
the algorithm start from first wish and search to compatible gesture if find it do it and then stop search.

[Bijan Binaee (bijanbina)]

also for firefox you should change these wishes
    <wish gesture="Drag" fingers="2">
      <action name="action5" when="update">
        <trigger prop="delta y" min="20" max="80"/>
        <key>Page_Up</key>
      </action>
    </wish>
    <wish gesture="Drag" fingers="2">
      <action name="action6" when="update">
        <trigger prop="delta y" min="-80" max="-20"/>
        <key>Page_Down</key>
      </action>
to something like this
    <wish gesture="Drag" fingers="2">
      <action name="action5" when="update">
        <trigger prop="delta y" min="20" max="80"/>
        <button>4</button>
      </action>
    </wish>
    <wish gesture="Drag" fingers="2">
      <action name="action6" when="update">
        <trigger prop="delta y" min="-80" max="-20"/>
        <button>5</button>
      </action>
    </wish>

because page up and page down key move too fast!

The proposed fix has been proposed but yet not been committed to the ginn project. Reverting status change.
