Added additional bitmap creation in ImageHelper.createThumbnailFromUri to create a pixel-accurate cutdown of the image.

Change some of the EXIF method to return Integers instead of Strings.
If a resized image was not able to be created, upload the full size image and add some CSS that will force it to resize in the browser.
Renamed a variable.
Return 0 if exifinterface fails.
Adding a MixPanel event for Out of Memory Errors encountered when resizing bitmaps, so we can measure severity of #1122.
Merge pull request #1134 from wordpress-mobile/issue/1122-oom-bitmap

Better Bitmap Out of Memory Handling
