centralize script handling logic (#477)
currently the logic of when to open/close script is scattered around the entire code-base which is both ugly and error-prone. this patch centralizes script handling by remembering the relevant information on each redraw and then comparing it with the previous information to figure out whether something changed or not. this also fixes a bug where scripts weren't being called in thumbnail mode when mouse was used for selecting a different image.
