Support initial_zoom , maybe other options via shortcode

[JoeGermuska]

On the support forums, a user asked whether initial_zoom and zoom_sequence were supported.

They are not. They could be. Here's the relevant part of the code:

TimelineJS-Wordpress-Plugin/knightlab-timeline.php

Lines 36 to 54 in 7ea6b9e

	extract(shortcode_atts(
	array(
	'title' => '',
	'width' => '100%',
	'height' => 650,
	'font' => '',
	'lang' => 'en',
	'src'=> '',
	'start_at_end' => 'false',
	'hash_bookmark' => 'false',
	'debug' => 'false',
	'maptype' => '',
	'start_at_slide' => 0,
	'start_zoom_adjust' => null,
	'version' => '',
	'script_path' => plugin_dir_url( __FILE__)
	), $atts
	));
