* Prettify number of issues - Use the PrettyNumber function to add commas in large amount of issues. * Use client-side formatting * prettify on both server and client * remove unused i18n entries * handle more cases, support other int types in PrettyNumber * specify locale to avoid issues with node default locale * remove superfluos argument * introduce template helper, octicon tweaks, js refactor * Update modules/templates/helper.go * Apply some suggestions. * Add comment * Update templates/user/dashboard/issues.tmpl Co-authored-by: silverwind <me@silverwind.io> Co-authored-by: silverwind <me@silverwind.io> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
