Merge branch 'release/0.9.9' into develop
Correct project title in README
Another little README tweak
Update README with better symbol settings instructions
Fix typo in Stylet.Samples.RedditBrowser
Change how Stylet.Samples.RedditBrowser's SubredditViewModel closes itself
Rename LambdaComparer to LambdaEqualityComparer, and create actual LambdaComparer
Extend BoolToVisibilityConverter to handle more types
Add channels to the EventAggregator
Move MessageBoxView into Xaml
Remove the WeakEventManager, as it was too complex

It's replaced with a BindWeak extension method, similar to the existing
Bind. This rejects delegates with compiler-generated targets
Change the handler type for Bind and BindWeak, to include the sender and property name
Move MessageBoxView back out of Xaml, so it's in the same location as its VM
Add more system type aliases
Split out the type which were all previously in StyletIoCContainer.cs
Remove and sort usings
Fix bug in BoolToVisibilityConverter, causing exception with some argument types
Replace the isSingleton bool with a RegistrationFactory lambda, which should more easily allow other scopes
Add OnStart hook for when Stylet starts up, and rename the existing hooks to avoid confusion
Remove all instances of 'throw new Exception'
