Adding a default branch argument to the updateProject method.

The default branch controls which branch is displayed when a
user navigates to a project in Gitlab.  Typically Gitlab will

prior to creating the master or development branches, it may
be necessary to use this "default_branch" field to specify
the default branch that should be displayed to users.
