Template: remove the following parameters from the t()-method: $fallbacktag, $fallbackdefault, $striptags

Backwards compatibility with the previous style is preserved, but will write a

Uses of $fallbacktag should be replaced with calls to the getTag()-method.
The $fallbackdefault and $striptags parameters didn't have any in-tree users.
