Replace supported image extension list with image detection via MagickImageInfo. (#818)

Browse Source 
* Replace supported image extension list with image detection via MagickImageInfo.

* Change ImageViewer priority to -4.
Change VideoViewer priority to -3 and detect audio/video via MediaInfo instead of file extensions.

* Make mediaInfo a class static and initialize once.
Add some notes about MediaInfo Open and Close.

* Remove try/catch from Prepare and let it be handled in caller.
If there was an exception due to MediaInfo it would have already occurred in CanHandle.

* Upgrade ImageMagick to latest

* Only check extension for well known image and animated image types.
For other image formats, let ImageMagick try to detect by file content.
Upgrade to latest Magick.NET
