Add thread id to title

[ezechiele81]

hello.
I tried to do several searches with "postid title" "threadid title" "thread title number" ...
but I have not found what I want.
We have problems with duplicate title in the title tag so I entered the name of the forum in addition to the name of the thread.
but not enough.
I must also add the number of tread in <title>

My <title> in showthread templates is:

<title>{vb:raw thread.prefix_plain_html} {vb:raw thread.title} - {vb:raw forumTitle}<vb:if condition="$pagenumber > '1'"> - {vb:rawphrase page_x, {vb:raw pagenumber}}</vb:if></title>

Thanks to all
