Assemblies loading for Policy Evaluator and Checkintool improved. Refs #258
Move the path resolver to the constructor.

This will ensure that it's in place before evaluating
checkin policies, which is when it is needed, without
expanding the interface of ITfsHelper.
Check to install resolver only once
Correct case where one repository path is included in another one

When we are in a remote that have tfs path $/Project/MyBranch_1
and that we search the path in the git repository of the file $/Project/MyBranch_1.1/file.txt
we must return null (because this file is owned by the other remote $/Project/MyBranch_1.1)

In the past, we return ".1/file.txt" as relative path.

We should also managed well, folder path "$/Project/MyBranch_1.1" compare to "$/Project/MyBranch_1"
Same thing when using Subtree command

Assemblies loading for Policy Evaluator and Checkintool improved
Find the REAL root changeset when there is rename changeset(s) and get the list of successive branches...

and manage case where using flag '--nofetch' but with renamed branches
Add debug datas
Manage rename tfs branch the good way
Retrieve also deleted tfs branches if needed
Don't create git branch when renamed branch!
Delete remotes corresponding to renamed branches
Manage and don't stop initializing branches if some fails (and report at the end of the process)
Finding root changeset: better finding of renaming

- Protection against find itself as parent branch
- Support of renaming of renaming
- keep the last "renamed" merge is important when no root found (with what is supposed to be the root branch)

+ catch problem when finding root changesets
Correct UnitTests
Move InitBranch() in the GitTfsRemote (to be able to init one from there!)
write what should be done...
being able to fetch until a changeset is reached
Create on the fly the missing remote (with fake Sha1 for the moment)
