can't add/delete Addon Template
In 3.1, editing a Reseller (or Client) you can't add an Addon Template, the 'Add additional template' button just creates a javascript error.
A quick fix for that which allows adding templates in interface/web/themes/default/assets/javascripts/ispconfig.js line 510, change 'new_tpl_add_id' to 'ISPConfig.new_tpl_add_id'. But even then the delete icon is not working / doesn't display (it's 0 width).
I don't know if this is a css change that should be using 'icon icon-delete' now or what's going on, so just filing the bug...
