ignored by the ignore-paths option. For example if you want to ignore all
exe files except the .nuget/NuGet.exe file, you can add exe$ to the ignore-paths
and ^\.nuget to the ignore-except.
Added --except-regex command line option to RemoteOptions to set ignore-except
config.
New tfs-remotes for branches now will copy the ignore-paths and ingore-except
options from the default tfs remote.
(The client lib will only use it as a fallback.)
Removed the useless username. It seems like there are other ways that the
user/pass can be gotten from the user and/or stored.
Also cleaned up some method access specs.
