Adding Mvc5 Test
Merge branch 'dev' of https://github.com/perploug/ImageProcessor into dev
v1.8.3 & v.3.1.0
v3.1.1.0 Fixes #36

Permissions issues within the DotNetOpenAuth library when used in
conjunction with Mvc5 were causing a ReflectionTypeLoadException when
attempting to autoload all plugins. Behaviour is now changed so that if
this fails, plugins will load from the configuration instead.
