install.ps1: ask which drive to install to

Browse Source 
Lists local fixed drives with free space and lets the player pick one by
number or letter. Enter keeps the previous location on the system drive
(%USERPROFILE%\mc-lan-party), so existing installs are still found;
other drives install to <drive>:\mc-lan-party. Warns under 3 GB free.
