[ALPHA]

1. Changed logic of loading core classes - now script just parse
app/core/classes directory for *.php files and includes it, that means
you don't need to call function loadCore() - renamed "loadClass()"
function - when you added new core class
2. Changed logic of getResourceData (just upgraded it without any attack
to non-core scripts)
3. Fixed some problems with adding/editing news in admin panel
4. Added resources module to admin panel
