Implementation of per-user .hgignore.
Reference: http://www.selenic.com/mercurial/bts/issue166
If the [ui] section of .hgrc contains keys like "ignore" or
"ignore.something", the values corresponding to these keys are
treated as per-user hgignore files. These hgignore files apply to all
repositories used by that user.
