Not really sure what the best way to fix this is. I've got it working, but looking for better ideas.

Change tools/mod_perl_startup.pl to set a ENV variable for the scripts directory.

Change bootstrap to use the $ENV{FOSWIKI_SCRIPTS} if defined

Still some issues. Because the BEGIN block runs before any path information is available, the bootstrap gets the DefaultUrlHost and other settings wrong. We probably need to run bootstrap a 2nd time in the Foswiki::new(), so that the paths can be properly applied.

This is probably the same with FastCGI.

These are hopefully fixed. Need validation.
