We already have {{SERVER}}.
This variable can have different values depending on how the wiki is accessed.
Examples: http://localhost , http://internal.network or http://www.domain.tld
In e-mails sent by the wiki (especially enotifs) and in the text templates for
them, it would be useful to have a fixed variable, which the Sysop can set to
{{SERVER}} (installation default) or to a different value, which then reflects
the external server address such as http://www.domain.tld and is substituted.
I hereby propose to implement an additional variable with the name
{{SERVER_EXTERN}} which can be used by the wiki software internally (example:
UserMailer.php), MediaWiki: pages and any wiki page
