Feature request: Importing labels

[al0fdf]

Would be nice to be able to import labels.
A few notes regarding the implementation of this:

• Get the <text> tag under the object:

  <object id="129" x="208" y="768" width="57.3707" height="17.7732">
     <text pixelsize="12">TUTORIAL_JUMP</text>
  </object>
  

• Store x, y, width, height
• Compute label rect position and rect size from x,y,w,h
• For setting font color of a label:
  label.set("custom_colors/font_color", Color.black)
• For halign and valign:

  {
      "center": Label.ALIGN_CENTER,
      "right": Label.ALIGN_RIGHT,
      "justify": Label.ALIGN_FILL,
      "left": Label.ALIGN_LEFT,
  }
  

  {
      "center": Label.VALIGN_CENTER,
      "bottom": Label.VALIGN_BOTTOM,
      "top": Label.VALIGN_TOP,
  }
