map meta filter

filter to adjust where map UI options are shown in admin
kill viewstart when top of screen is reached

stop audio and video from playing if viewstart is activated and the player reaches the top of the screen
introduce viewend="" attribute for audio and video component

this compliments the viewstart attribute. viewend="on" will stop the audio/video component when scrolled out of view
three new filters

new filters to adjust timeline and chapter component nav classes

this makes it way easier for theme compatibility
modify previous filters to allow classes and id's to be passed
remove failing android user agent sniffing

in this case since this was failing it's safe to assume the feature wasn't being utilized. we'll let most user agent sniffing be handled case by case, by the theme author
