Enable multi repo use: make bitbucket-issue-manager work with repo specificed in my project's .git directory

[hanselke]

inside the .git/config folder

there would be one or more [remote "x"] url = https://bitbucket.org/project/name

by default, make it pick up x=origin as origin is the default standard people work with.

By doing this instead of reading it off bitbucket-issue-manager's config, you can allow this tool to work across many project directories.

even if you are working on a single project, you would have smaller components like published npm modules that you need to manage in a different repo.

bitbucket accepts commit -m 'resolve #issueid' in order to automatically close repos, so that is not needed
