[TIMOB-8812] BlackBerry: Implement important Titanium.UI.Clipboard functionality

// Custom application MIME types for clipboard data.
const kTypeText = 'application/x-text',
      kTypeBlob = 'application/x-blob';

var win = Ti.UI.createWindow({
	backgroundColor: 'red',
	layout: 'vertical'
});

// Displays the current "plain text" in the clipboard.
var textLabel = Ti.UI.createLabel({
	text: Ti.UI.Clipboard.getText() || "No text."
});
win.add(textLabel);

// Displays the current custom text in the clipboard.
var customTextLabel = Ti.UI.createLabel({
	text: (Ti.UI.Clipboard.getData(kTypeText) || {text: 'No custom text.'}).text
});
win.add(customTextLabel);

// Displays the current custom blob data in the clipboard.
var customBlobLabel = Ti.UI.createLabel({
	text: (Ti.UI.Clipboard.getData(kTypeBlob) || {text: 'No custom blob.'}).text
});
win.add(customBlobLabel);

// Clears all data in clipboard.
var clearDataButton = Ti.UI.createButton({
	title: 'Clear Data'
});
clearDataButton.addEventListener('click', function() {
	Ti.UI.Clipboard.clearData();
});
win.add(clearDataButton);

// Paste some text into the clipboard.
var setTextButton = Ti.UI.createButton({
	title: 'Set Text'
});
setTextButton.addEventListener('click', function() {
	Ti.UI.Clipboard.setText('Text Inserted!');
});
win.add(setTextButton);

// Paste custom application data into the clipboard.
var setCustomDataButton = Ti.UI.createButton({
	title: 'Set Custom Data'
});
setCustomDataButton.addEventListener('click', function() {
	Ti.UI.Clipboard.setData(kTypeText, 'Custom Text!');

	var buffer = Ti.createBuffer({length: 16});
	'Custom Blob!'.split('').forEach(function(char, index) {
		buffer.fill(char.charCodeAt(0), index, 1);
	});
	Ti.UI.Clipboard.setData(kTypeBlob, buffer.toBlob());
});
win.add(setCustomDataButton);

win.open();
