config: add a new [command-templates] section for templates defined by hg The existing `[templates]` section lets the user define their own keys and then refer to them on the command line with `-T`. There are many cases where hg wants to use a user-defined template with a given name, such as `ui.logtemplate` and `ui.mergemarkertemplate`. This patch starts moving such configs in a common section by moving `ui.logtemplate` to `command-templates.log` (with an alias from the old name, of course).

i18n: fix coding tag unsupported by xgettext Running `make update-pot` currently fails with the following error: xgettext: mercurial/metadata.py:1: Unknown encoding "utf8". Proceeding with ASCII instead. xgettext: Non-ASCII string at mercurial/metadata.py:311.

py3: hggettext `itervalues()` is only available on Python 2. Since this script doesn't currently refer to the main Mercurial modules, and as a result doesn't have easy access to the `pycompat` module, I simply changed it to use `value()` instead. Although this allocates a list on Python 2, I'd consider that acceptable for a utility script; Mercurial doesn't have all _that_ many commands anyway.
