Configurator: Use mpextended.com domain for update checker (fixes #364)
MyFilms: Open MyFilms.xml shared (fixes #363)
Configurator: Show message when cache has been cleared (fixes #362)
WebMP: Don't require seasons to have a title

That's because they don't have one. This broke the TV Shows section of
WebMP. Oops.
Streaming: Recreate extracted image in cache if source file is newer (closes #367)

(cherry picked from commit ac852491a856cb6845297ebe305e317d25dad92b)
WSS: Close media and artwork files after usage
WebMP: Fix race conditions during skin loading
DevTool: Use different exclusion settings for different Wix FS files

This also adds the WebMP Skins and Plugins folder to the exclusion list, so that
we don't accidentally ship skins or plugins in the installers.
WebMP: Don't use album player if a video-enabled streaming profile is chosen (fixes #366)
WebMP: Disable stream authentication when authentication is disabled
WebMP installers: Create Skins and Plugins folders
TAS: Don't crash when LogoDownloader throws exceptions
Log instead of crash when a TPL task throws an exception
WebMP: Remove custom HTTP handlers for views, skins and plugins

If we don't touch the default handlers for these files, IIS can handle them without
any intervention from ASP.NET, which is faster. We block access to the cshtml and
executable files with IIS request filtering.

This also avoids the need for skins to place a custom web.config file in their Content
directory to make them accessible.
Logger: Don't crash when logging a null exception
WSS: Escape output filename for image extraction

This fixes image extraction on Windows XP.
WebMP: Allow Images/calendar.gif image to be overridden
Library: Remove whatismyip.com as provider for external IP

They removed the ASP script.
Library: Rewrite external IP detection to skip unparseable addresses

We shouldn't error out on an unparseable address, but just skip the provider and try the
next one.
