LogProfiler and the web project to use a web profiler (MiniProfiler). Fixes medium trust implementation,
adds performance check for binding to begin request, changes Web profiler over to be decoupled from the
umbraco application objects (binds to events by itself)
signatures of IApplicationEventHandler methods to accept an UmbracoApplicationBase object instead of UmbracoApplication. This allows
us to execute all IApplicationEventHandler's outside of the web context. Added unit test to support booting the application outside of the
web context.
