cmdutil: mark string for translation

util: use "is" for True/False/None comparisons

remove: warn if unversionned files are specified (issue1454)

fetch: allow -r for remote repos

filelog encoding: move the encoding/decoding into store the escaping of directories ending with .i or .d doesn't really belong to filelog. we put the encoding/decoding in store instead, for backwards compat, streamclone and the fncache file format still uses the partially encoded filenames.

store: refactor the fncache handling put all the fncache file writing and reading in the same place.

hgweb: make hgwebdir handle dict/list paths the same as config paths Before this patch, the only way to get hgwebdir to honor the recursive paths was to create a config object or a config file with the recursive paths in it. This patch makes hgwebdir treat paths the same whether passed in as a list, tuple, config or however hgwebdir supports passing paths.
