Icons Improvements

Couple things for the Icons of goal/subgoal:

• Would be great to have a search bar in the life area / goal/ subgoal icons (searching doctor would have the doctor icon show up)

• Would be great to have more options in icons, and perhaps even emojis

• When you set a certain image as the head picture of a goal/subgoal/life area, the default icon when searching for it is the "target" icon.
  It'd be great to be able to attach both pictures and icons to a given goal. Or the image we attached to it stay stuck to the goal. Just so ideally, if we modify it, it's not the standard "target" icon.
