Alias domain options missing help in server templates

Re: Bug #119

When clicking on the following two options in the server templates, the below missing file errors appear:

1) Automatically create alias domain:

Error: Failed to read help file /usr/libexec/webmin/virtual-server/help/template_domalias.html

2) Suffix for alias domain:

Error: Failed to read help file /usr/libexec/webmin/virtual-server/help/template_domalias_type.html
