libseed-list something broke with upgrade

[Jonatan Liljedahl <lijon kymatica com>]

I just recompiled Seed from current git, after upgrading to ubuntu 10.04 
and upgrading some gobject-introspection stuff to be able to compile the 
latest Seed.

It built fine, but something happened with import.searchPath. With this 
file:

// foo.js
print(imports.searchPath);
print(__script_path__);
// EOF

and a modified extensions/Seed.js with debug-prints like this:

print("Running Seed.js");
if(!imports.searchPath || (imports.searchPath.length == 0))
{
	print("setting searchPath..");
	imports.searchPath = [ "/usr/share/gnome-js",
	                       "/usr/local/lib/seed",
	                       "/usr/local/share/seed",
	                       "/usr/local/lib/seed",
	                       "/usr/local/share/seed",
	                       "/usr/lib/seed",
	                       "/usr/share/seed" ];

	if(Seed.argv.length > 1)
	{
		print("Setting __script_path__");
		__script_path__ = GLib.path_get_dirname(Seed.argv[1]);
...

I get this output when running 'seed foo.js':

Running Seed.js
setting searchPath..
Setting __script_path__
/usr/share/gnome-js,/usr/local/lib/seed,/usr/local/share/seed,/usr/local/lib/seed,/usr/local/share/seed,/usr/lib/seed,/usr/share/seed

** (seed:19398): CRITICAL **: Line 2 in foo.js: ReferenceError Can't 
find variable: __script_path__

As you see, __script_path__ didn't stick and '.' didn't get added to 
searchPath.
Also I noticed that the 'GLib' variable is no longer automatically 
available in new contexts as it used to be (since Seed.js exports it as 
a toplevel variable). What's going on? This situation breaks the import 
system...
