Add configuration option to not add weblinks

In some situations a site may want to install gitiles in Gerrit,
but not have weblinks from the Gerrit UI.

Add a new configuration option:

    noWebLinks = true

which, when set, will prevent the weblinks from being added.

The default is unset, meaning the weblinks are displayed as before.
