hgwebdir: refresh configuration periodically The old default behaviour of hgwebdir was to maintain a list of repositories permanently. This interacted badly with persistent application hosting software such as WSGI containers. If a new repository was published, it would potentially never appear in the top-level list of repositories. This change causes the hgwebdir configuration and list of repositories served to be refreshed periodically (at most every 20 seconds).
