loading library code

using "load p18f1220.f" from a file not in the staapl/pic18 directory
doesn't work..  it does work when using staaplc, but not when using
the require form from scheme.

EDIT: this is because the module level code has no concept of load
path: it only uses absolute and relative references.  The prj/pic18
version does have this functionality, and is the preferred way of
using the compiler.
