Autoreload works if mtime is newer, but not older.

The apache.import_module() method only reloads a Python module if the modification time of the file on disk is newer. This means that if one restores an old version of a file from backup, eg., by using "mv" command from another location, it will not reload it and it is necessary to touch the file or restart Apache.

The check in apache.py, instead of being just:

if mtime > oldmtime:

could perhaps be:

if mtime != oldmtime:

I don't believe this would cause any wider issues, but might be due some thought first.

The various settings of mtime and oldmtime above that in the code, ie., to 0 or 1, will also have to be reviewed to ensure this change doesn't break anything.
