Add SetTitle support about tcell HOT 4 CLOSED

Apparently these sequences, like the mouse sequences, are not part of any terminfo standard.

Here's some useful information: http://tldp.org/HOWTO/Xterm-Title-6.html
And for screen: https://www.gnu.org/software/screen/manual/html_node/Control-Sequences.html
And for Eterm: http://www.cs.columbia.edu/~ricardo/misc/Eterm_reference.html

Well, it turns out that we have no way to obtain the old title on Xterm, because of security considerations. Furthermore, applications that modify the terminal window are rare -- neither Emacs nor Vim does this for instance.

So, given that, I'm declining to implement this.

i just add a

os.Stdout.Write([]byte("\x1b]1;"+title+"\a\x1b]2;"+title+"\a"))

as first line in my main() to solve this for xterms and compatible. its not without dangers as other terminals may react unexpected.

Having the ability to change the title would be pretty useful in applications like Senpai.
It could, for example, show the currently selected channel + number of unread messages or even animate the title on highlights via a ticker interval which would then be reflected by a desktop panel.

Edit:
Seems terminfo provides tsl and fsl variables for this, so the full format would be {tsl}some title{fsl}:

test -n "$(tput tsl)" && printf "%s" "$(tput tsl)some title$(tput fsl)"

The absence of these could thus be used for feature detection (maybe in combination with hs).

@gdamore Would you be open to accept a PR implementing SetTitle() using this strategy?
