hgwebdir: ignore hgrc parse errors while building the index page An error in the .hg/hgrc file from a repository would prevent the following repos from being shown in the index page. The IOError handling was unnecessary - it's already handled in readconfig. This should fix issue731. The error in the .hg/hgrc file will still prevent the repo from being exported with hgweb.
