Emoji & Symbol Picker

Adds ability to input emoji and symbol characters via picker popup which is accessible using ALT+` (ALT and backquote) keyboard shortcut (configurable in the script). Character will be generated at the (blinking) cursor. If there's text selected, the character will replace the selection. Note: this script will not work on inputboxes whose keyboard inputs is script driven. e.g. WYSIWYG text boxes.
