[install.sh]
Fixed the following issues : - The password prompt went all wonky if password was wrong - The password prompt did not use system password cache and kept asking for password again on reruns of script - Installation failed if the script was initially ran by "sudo" due to inability to preserve ownership of files during cp commands - Security issue where the password prompt could be interrupted (Ctrl+C) and rerun without sleeping for few seconds first just like normal sudo failure in terminal - The sudo command would no longer accept password from ANY commands system-wide if wrong password was given to the install script enough times!! (the only fix would be restarting the system)
