Please leave the cursor the way it was

[ghost]

Summary:
The "tput cvvis" command makes the cursor very visible which is sometimes too much.
The "tput cnorm" command makes the cursor look normal.

Reproducing:

1. run cloud-in-a-box.sh on the console or other terminal where "tput cvvis" is very different from "tput cnorm".
2. when the script is complete or interrupted with ^c the cursor will look strange.

Expected:

1. run cloud-in-a-box.sh on the console or other terminal where "tput cvvis" is very different from "tput cnorm".
2. when the script is complete or interrupted with ^c the cursor will look like it normally does.
