Subject: [PATCH] Clarify beam_load error message on file/module mismatch

This is particularly important in case insensitive filesystems,
where attempting to invoke a module with the wrong case leads
to confusing error messages:

    1> erlpress_core:foo().
    beam/beam_load.c(1428): Error loading module 'erlpress_core':
      module name in object code is erlPress_core

    Loading of erlPress_core.beam failed: :badfile

This commit replaces object code by BEAM file and improves
the readability of the message.
