[Ecls-list] Bug fixes

[Juan Jose Garcia-Ripoll]

 - LOAD no longer defaults to loading a file as binary if the file type is
   different from FAS or FASL. Use either SI:LOAD-BINARY or configure the
   variable SI:*LOAD-HOOKS* accordingly to load FASL files with unusual
   extensions.

This solves the issues found by birulevo about defsystem and asdf not
working on windows.
