Checks for existence of /opt, and creates it if it doesn't exist.

Added "--withturbojpeg" switch.
Added "--withpulse" switch.
Changed the "--withsound" switch to "--withsimplesound", to avoid potential confusion.
Added further explanations for the jpeg and turbojpeg modules/libraries.
Ensures relevant -dev libraries are installed for the various switches.
Tidied up some indenting in the switch-parser and removed some redundant commenting.
