  An on-screen virtual keyboard embedded within the browser window which
  will popup when a specified entry field is focused. The user can then
  type and preview their input before Accepting or Canceling.
  
  As a plugin to jQuery UI styling and theme will automatically
  match that used by jQuery UI with the exception of the required
  CSS listed below.
  
  Requires:
  	jQuery
  	jQuery UI (position utility only) & CSS
  
  Usage:
  	$('input[type=text], input[type=password], textarea')
  		.keyboard({
  			layout:"qwerty",
  			customLayout: {
  				'default': [
  					"q w e r t y {bksp}",
  					"s a m p l e {shift}",
  					"{accept} {space} {cancel}"
  				],
  				'shift' : [
  					"Q W E R T Y {bksp}",
  					"S A M P L E {shift}",
  					"{accept} {space} {cancel}"
  				]
  			}
  		});
  
  Options:
  	layout
  		[String] specify which keyboard layout to use
  		qwerty - Standard QWERTY layout (Default)
  		international - US international layout
  		alpha  - Alphabetical layout
  		dvorak - Dvorak Simplified layout
  		num    - Numerical (ten-key) layout
  		custom - Uses a custom layout as defined by the customLayout option
  
  	customLayout
  		[Object] Specify a custom layout
  			An Object containing a set of key:value pairs, each key is a keyset.
  			The key can be one to four rows (default, shifted, alt and alt-shift) or any number of meta key sets (meta1, meta2, etc).
  			The value is an array with string elements of which each defines a new keyboard row.
  			Each string element must have each character or key seperated by a space.
  			To include an action key, select the desired one from the list below, or define your own by adding it to the $.keyboard.keyaction variable
  			In the list below where two special/"Action" keys are shown, both keys have the same action but different appearances (abbreviated/full name keys).
  			Special/"Action" keys include:
  				{a}, {accept} - Updates element value and closes keyboard
  				{alt},{altgr} - AltGr for International keyboard
  				{b}, {bksp}   - Backspace
  				{c}, {cancel} - Clears changes and closes keyboard
  				{clear}       - Clear input window - used in num pad
  				{combo}       - Toggle combo (diacritic) key
  				{dec}         - Decimal for numeric entry, only allows one decimal (optional use in num pad)
  				{e}, {enter}  - Return/New Line
  				{lock}        - Caps lock key
  				{meta#}       - Meta keys that change the key set (# can be any integer)
  				{next}        - Switch to next keyboard input/textarea
  				{prev}        - Switch to previous keyboard input/textarea
  				{s}, {shift}  - Shift
  				{sign}        - Change sign of numeric entry (positive or negative)
  				{sp:#}        - Replace # with a numerical value, adds blank space, value of 1 ~ width of one key
  				{space}       - Spacebar
  				{t}, {tab}    - Tab
  
  CSS:

  	.ui-keyboard-has-focus { z-index: 16001; }

  	.ui-keyboard-preview-wrapper { text-align: center; }
  	.ui-keyboard-preview { text-align: left; margin: 0 0 3px 0; display: inline; width: 99%;} - width is calculated in IE, since 99% = 99% full browser width
  	.ui-keyboard-keyset { text-align: center; white-space: nowrap; }

  	.ui-keyboard-placeholder { color: #888; }
  	.ui-keyboard-nokeyboard { color: #888; border-color: #888; } - disabled or readonly inputs, or use input[disabled='disabled'] { color: #f00; }
