CustomConfigParser.getlocaleval() loads "pythonfile" at each call.
Besides unnecessary IO, in case that dynamic_folderfilter is true, the
code in "pythonfile" would behave stateless, since it is re-initialized
at each call of getlocaleval(), i.e., at every sync. Fix that by keeping
a singleton copy of localeval in CustomConfigParser after the first call
of getlocaleval().
