Updates for the new boot URL loading mechanism.
Updated for the new output of the bootcompiler.
Accept a Base *functor*, and bind Base.'Base' = Base.
Added Compile.oz to the files to be compiled.

This is the batch, aka standalone compiler.
Boot-compile functors in a regular cache as .ozf files.

With this we can simply rely on Resolve to find the correct
path to the boot-compiled functors. Moreover, it can find
(non-boot)-compiled functors if they exist.
Made it installable again. Also supports ozc!
Slight improvement of the build script.
