Remove the unsecure prompt for password

[dan-forsberg]

Instead of asking the user for a password and doing things like echo $PASSWORD | sudo ... just do sudo .... Some users might've setup sudo to not require the password, so asking for a password is meaningless in those cases. Plus if sudo DOES require a password you only need to enter it once, and sudo has it cached.

Another gaping issue I discovered, as someone who's setup sudo to not prompt for a password, is that when the installation tried to install packages pacman did the regular ":: Proceed with installation? [Y/n] "... my password was printed as a response in clear text.

Yes, you're right about this.

Not sure if I get this. You don't have a password set up but still it gets printed out? I don't run Arch on any of my machines but I haven't observed this kind of issue anywhere else (Fedora, Ubuntu).

To be honest I am not spending much time around the installation script. If you have some spare time to provide a fix, pull request will be more than welcome :)

You can have a password set while not requiring a password to be used with sudo. Maybe that clears it up.
