#1120 Possible x64 issue in source

bugfix (702)

We've been chasing issues running Python-Ogre on 64 bit systems (Linux specifically) and have fond one issue in resource group manager where getScriptPatterns returns a huge (2^31) number. As an example this patch works around it (obvious not a complete/good fix at all)

        // Get all the patterns and search them
        const StringVector& patterns = su->getScriptPatterns\(\);

+ if(patterns.size() > 20) {

I don't have a system to test on however in reviewing the Ogre source I can see one area that might be a problem and hence have attached a patch for to fix BillboardChain::SEGMENT_EMPTY which is defined with a 32 bit magic number...

This is UNTESTED (I don't have a 64 bit system) -- sorry.... :(

    Since size_t is unsigned I don't want to initialise it with -1, instead I've used std::numeric_limits<size_t>::max(), which should deal with varying sizes.

    I don't really have any idea about your getScriptPatterns() issue though...
