Instead of creating a 'Tinyblast' button bellow the other Playblast Options buttons, 'Playblast' button is now replaced with 'Tinyblast' and uses the custom_playblast function
Learned some Qt and didn't like how I handled the 'Tinyblast' button. Now instead of a big ole 'Tinyblast' button underneath the other 'Playblast' buttons, Tinyblast overrides the default 'Playblast' button.
