Heaven Update

• Added support for Bitmap fills
  They are mostly used as proxies for 9slice movieclips, and 9slice was used quite a bit in some important files, so now you can easily export them back yay
• Added Export name replacing
  Another very important feature. Now, using External File option, you can replace or overwrite export name in external file from your document, so you can literally replace some content inside the file.
• Changed symbol selection algorithm
  Improved behavior of symbol type selection, so there should be less garbage in final file and overall export time should decrease slightly
