* Consolidate Nuget packages

* Performance improvements via caching of Principals and PrincipalContexts

This commit brings some performance improvements by implementing some
basic caching of Principal and PrincipalContext objects instead of
init'ing them every time. Saves about 2 seconds per init from my usage
so far.

Expiry right now is hard-coded to 10 minutes, should really shift this
to a web.config value.

* Performance improvements via caching of PrincipalSearchResults

This commit provides huge performance gains by caching the results of
calls to GroupPrincipal.GetMembers(true) by enumerating the
PrincipalSearchResults object and storing it. Normally this class lazy
loads the results, so the enum is triggered up front and stored for
later use. On my use case this sped up authorization calls from 10+
seconds to under a second.

Like the previous commit, the cache is set to expire after 10 minutes -
I will endeavour to move this out into web.config.

* Add configuration keys for AD cache expiry durations

This commit shifts the hard-coded cache expiry for Active Directory
objects of 10 minutes into configurable options.

The keys are:
ActiveDirectoryGroupQueryCacheExpiry
ActiveDirectoryPrincipalCacheExpiry

They will be parsed into TimeSpan objects by
ConfigurationHelper.ParseTimeSpanOrDefault (defaulting to 10 minutes).

* Cleanup for PR

This commit addresses some notes in the PR:
- Locks sections have been fixed up and slightly improved in terms of
  readability
- Implement IDisposable on cache objects, most important on
  ADCachedSearchResult as it will dispose the enumerated principals
- Formatting tidy-up, braces

* Amendments for IDisposable implementations on cache objects

Replace Disposing with _Disposing and use nameof when retrieving
property name as part of throwing ObjectDisposedExceptions.

* Correct dispose exception throw, code to use corefx style

- throw new ObjectDisposedException refers to the class rather than the
  property
- update private and private static member identifiers to follow corefx
  style conventions

Changes based on PR feedback

The change to the repository/index behaviour impacted a test.
I updated the expected url after the logout and changed the repository index to return the home/index url when there are no anonymous repositories to keep the behaviour consistant with the previous flow.

Change the repository index anonymuos user behaviour based on the existance of an Anonymous enabled repository

When there are no Anonymous Repositories goto jail, I mean the logon screen for Anonymous users.  Otherwise goto the repsitory index.
