feat(android): add rotation to blob

[m1ga]

Adding a rotation value to Ti.Blob. If it is available in the blob it will return it:

const win = Ti.UI.createWindow({layout:"vertical"});
const btn1 = Ti.UI.createButton({title:"1"})
const btn2 = Ti.UI.createButton({title:"2"})
const btn3 = Ti.UI.createButton({title:"3"})
win.add([btn1,btn2,btn3]);

btn1.addEventListener("click", function() {
	Ti.Media.openPhotoGallery({
		success: function(e) {
			console.log(e.media.rotation);
			console.log(e.media.width, "x", e.media.height);
			console.log(e.media.uprightWidth, "x", e.media.uprightHeight);
		}
	});
})
btn2.addEventListener("click", function() {
	Ti.Media.showCamera({
		success: function(e) {
			console.log(e.media.rotation);
			console.log(e.media.width, "x", e.media.height);
			console.log(e.media.uprightWidth, "x", e.media.uprightHeight);
		}
	});
})
btn3.addEventListener("click", function() {
  var file  = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, 'test.txt');
  console.log(file.read().rotation);
})
win.open();

Test:

• run the app (manually allow Camera permission!)
• click 1, select an image. Should most of the time return 0
• click 2, make an image in portrait or landscape mode and it should return a rotation value
• click 3, it should return undefined
