Fix more load/save bugs

[jdemeyer]

1. Remove all documentation about load filename, it should be load("filename").
2. src.sage.repl.load calls eval(!) on the filename, deprecate that behaviour.
3. The optional - internet tests in src/sage/repl/load.py are broken since Move preparsing, loading and attaching to src/sage/repl #17396.
4. Move loading of Fortran files to src/sage/repl/load.py.

LGTM, but there appears to be a minor merge conflict with #17533.

I'm seeing the warning when I use

sage: %runfile '/var/folders/d3/yxwv5yn5715fk31lq36lnk780000gn/T/sage24271vpp.sage' # loading region...
/Users/iandrus/vcs/sage/src/bin/sage-ipython:1: DeprecationWarning: using unevaluated expressions as argument to load() is dangerous and deprecated
See http://trac.sagemath.org/17654 for details.
  #!/usr/bin/env python

Is that expected? And I should change it to

load('/var/folders/d3/yxwv5yn5715fk31lq36lnk780000gn/T/sage24271vpp.sage')
