TeminalView updates

[Bruce Steers <bsteers4@xxxxxxxxx>]

Got some updates soon for terminal if you want them Ben.

Includes...
Finish WindowCommands  , previously I only did "\e[ t" commands 1 through
10 , have now done through to 23
only 24 is not done.

It adds TerminalView.IconTitle as 22 and 23 use terminal icon title text

TerminalScreen.CursorColor , changes cursor color using OSC \e]12;color\e\\
supporting using any of color values (gambas integer) , rgb(a) , and
constants
(i only found one of my other terminal programs supporting cursor color and
only using color words like "red")
I've used these methods..
echo -ne "\e]12;red\e\\"
echo -ne "\e]12;16711680\e\\"
echo -ne "\e]12;rgb:255,0,0,50\e\\"   , separators can be any of "/\:;,"
