You don't need to dynamic_cast everywhere to check things anymore.
Folders can have metadata now (currently not set up).
Metadata is now a public member variable instead of a function that
returns a pointer to make actually using const possible.
Made "DELETE" actually work in GuiMetaDataEd.
"DELETE" option also now asks if you're sure.
GuiMetaDataEd can be closed with the "b" button now.
GuiGameScraper now tries to put the cursor on the first game if there is
one when a search completes.
