Added extra check on modified field on btn_ok_Click so it doesn't try to apply changes when none have been made
Updated changelog with AnimationSheetView fix
Swapped way the bitmap is instantiated on PixelariaSaverLoader.LoadFrameFromStream() with a slighly faster cast
Fixed updateHash flag being ignored on Frame.setFrameBitmap(), throttling routines such as bundle loading speed considerably.
Updated changelog version and added message to reflect fixes made to the bundle loading speed
Reverted changes made to the PixelariaSaverLoader.LoadFrameFromStream() because the Bitmap constructor was needed due to images coming read-only from streams
Changed Graphics.FillRectangle() call to faster Graphics.Clear() on Frame.GenerateThumbnail()
Fixed typo on argument name on IPaintOperation and children classes
Fixed main form's title text's version being incorrectly displayed as 1.4
