i18n: extract doc string of each web commands as translatable one
Before this patch, doc string of each web commands isn't extracted as
translatable one, even though web commands are listed up in "hg help
hgweb".
This patch adds "mercurial/hgweb/webcommands.py" on to arguments of
"i18n/hggettext". "i18nfunctions" added into "webcommands.py" is used
by "i18n/hggettext" to get the list of functions having translatable
doc string.
