fix wrong renderlist feed permalink

when not using ugly urls, the feed permalink does not end up in the
expected location, and instead always behaves as if using ugly urls.

this fixes that behavior and inserts the feed xml file into the
directory as index.xml.

fix sanitizeRegex to not strip "dots"

sanitizeRegex was stripping dots in permalinks when generating
RenderIndexes (noted during feed/rss generation).

permalink was being set to `.../indexxml` instead of `.../index.xml`.

Adding "dot" to the regex whitelist fixed the issue.
