Quick Makefile change: unconditionally build everything.
Quick --help fixup and formatted string fixup for prices.
Removed unused parameter warnings throughout the program and fixed some formatting errors.
Removed strcasestr(). Woo, no more warnings (for now)!
Changed C-style comments to C++-style since I no onger need to worry about being safe with cgo.
Added the base system controller and made the header bar buttons do things.
