/**
 * @ngdoc service
 * @name $sanitize
 * @kind function
 *
 * @description
 *   The input is sanitized by parsing the HTML into tokens. All safe tokens (from a whitelist) are
 *   then serialized back to properly escaped html string. This means that no unsafe input can make
 *   it into the returned string, however, since our parser is more strict than a typical browser
 *   parser, it's possible that some obscure input, which would be recognized as valid HTML by a
 *   browser, won't make it through the sanitizer. The input may also contain SVG markup.
 *   The whitelist is configured using the functions `aHrefSanitizationWhitelist` and
 *   `imgSrcSanitizationWhitelist` of {@link ng.$compileProvider `$compileProvider`}.
 *
 * @param {string} html HTML input.
 * @returns {string} Sanitized HTML.

				a function that is executed on clicking on the button - this will allways be executed using ng-click and will
				overwrite any ng-click value in the display attribute.
				The function is passed a deferred object ($q.defer()), if this is wanted to be used `return false;` from the action and
				manually call `deferred.resolve();` elsewhere to notify the editor that the action has finished.
				restoreSelection is only defined if the rangy library is included and it can be called as `restoreSelection()` to restore the users
				selection in the WYSIWYG editor.
		display: [string]?
				Optional, an HTML element to be displayed as the button. The `scope` of the button is the tool definition object with some additional functions
				If set this will cause buttontext and iconclass to be ignored
		class: [string]?
				Optional, if set will override the taOptions.classes.toolbarButton class.
		buttontext: [string]?
				if this is defined it will replace the contents of the element contained in the `display` element
		iconclass: [string]?
				if this is defined an icon (<i>) will be appended to the `display` element with this string as it's class
		tooltiptext: [string]?
				Optional, a plain text description of the action, used for the title attribute of the action button in the toolbar by default.
		activestate: [function(commonElement)]?
				this function is called on every caret movement, if it returns true then the class taOptions.classes.toolbarButtonActive
				will be applied to the `display` element, else the class will be removed
		disabled: [function()]?
				if this function returns true then the tool will have the class taOptions.classes.disabled applied to it, else it will be removed
	Other functions available on the scope are:
		name: [string]
				the name of the tool, this is the first parameter passed into taRegisterTool
		isDisabled: [function()]
				returns true if the tool is disabled, false if it isn't
		displayActiveToolClass: [function(boolean)]
				returns true if the tool is 'active' in the currently focussed toolbar
		onElementSelect: [Object]
				This object contains the following key/value pairs and is used to trigger the ta-element-select event
				element: [String]
					an element name, will only trigger the onElementSelect action if the tagName of the element matches this string
				filter: [function(element)]?
					an optional filter that returns a boolean, if true it will trigger the onElementSelect.
				action: [function(event, element, editorScope)]
					the action that should be executed if the onElementSelect function runs

       * 'auto left-top' will check to see if there is enough space to the left
       * of the hostElem to fit the targetElem, if not place right (same for secondary
       * top placement).  Available space is calculated using the viewportOffset
       * function.
       *
       * @param {element} hostElem - The element to position against.
       * @param {element} targetElem - The element to position.
       * @param {string=} [placement=top] - The placement for the targetElem,
       *   default is 'top'. 'center' is assumed as secondary placement for
       *   'top', 'left', 'right', and 'bottom' placements.  Available placements are:

       *     <li>top-left</li>
