fix #938: check hasActivity in onPostExecute to avoid a npe
- Do not get the video mimeType from MimeTypeMap if it was already set in the cursor.
- When both cursor and MimeTypeMap fail to retrieve the mimeType, try to guess it by using URLConnection.
- When all of the previous method fail, set an empty mimeType.
Moved the code that retrieves the mimeType of a Media File to a utility method.

We can't live without mimeType.
Just renamed a variable
fix #943: add default dimens for theme dialog in case Utils.isXLarge() returns true even if the device width is < 720dp
Make sure the file has an extension, otherwise WordPress (server) can't match the mime type by using the filename provided in the request.
Fix #945 - extra protection to ensure we don't request more notes before the fragment's view has been created. Also optimized adding/clearing notes to avoid calling notifyDataSetChanged() more often than necessary.
fix #944: use long instead of int for comment ids
Split 'getMediaFilenameAndMimeType' in 2 different functions.
