Add test Resources directory
Add asbm test repository

Refer to http://nvie.com/posts/a-successful-git-branching-model/ for a
high level view of this repository layout
Add tooling to help working against test repositories
Improve GitFlowVersionFinder.FindVersion() test coverage
Enforce UpdateAssemblyInfo.Execute() test coverage
Make UpdateAssemblyInfo.Execute() require one remote when being run on a TeamCity agent
Ensure some basic requirements from the processed repository

Target repository should contain 'master' and 'develop' branches.
Ensure a feature branch is always created from the develop branch

Also make FeatureVersionFinder.FindFirstCommitOnBranch() not rely on the ref log to identify the first commit of the feature branch.
Un-ignore CanDetermineTheVersionFromAFetchedFeature() test
Drop .GetBranch() extension method

Local branches "develop" and "master" are expected to always exist. They're dynamically recreated from the fetched remote tracking branches when GitFlowVersion is being run on a TeamCity agent.
Ensure a hotfix branch is always created from the master branch
Ensure the examined repository HEAD isn't detached
Teach GitFlowVersion to detect GitHub pull requests in TeamCity context
Ensure a pull request is always created from the develop branch
Minor optimization
Merge pull request #32 from nulltoken/ntk/fix/detached_head

Resolving Pull Requests in TeamCity context
Teach UpdateAssemblyInfo to honor a faked TeamCity context
Tweak tests to force checkout and avoid conflicts
Merge pull request #45 from nulltoken/ntk/fix/faked_teamcity_context

Make GitFlowVersion tests play nice when being run by a TeamCity agent
Make TagsByDate() honor chained annotated tags
