Objectives: * Rename this.$ to this.$element * Rename this.$$ to this.$ * Get rid of the need to use this.frame.$$ * Rename OO.ui.Element.get$$ to OO.ui.Element.getJQuery Changes: (using Sublime Text regex patterns) * Replace "get$$" with "getJQuery" * Replace "\.(\$)([^\$a-zA-Z])" with ".$element$2" * Replace "\.(\$\$)" with ".$" * Replace "'$$'" with "'$'" * Set this.$ to null in constructor of OO.ui.Window * Set this.$ to this.frame.$ in initialize method of OO.ui.Window * Replace "\.(frame.\$)([^\$a-zA-Z])" with ".\$$2" Bonus: * Use this.$() in a bunch of places where $() was erroneously used Change-Id: If3d870124ab8d10f8223532cda95c2b2b075db94
