New Resource Management

Hi. I've been mainly working on the new resource management stuff because the old version was not flexible and we found it quite annoying when using it. The new system uses an array of strings to manage the names of data instead of enumeration. I've also been helping Stephen to get the collision side detection to work in MappyLoader. This took us about 2 days... I've also been making articles on the wiki. I was working on many small things last week. The showcase has been updated with new resource management support and camera showcase examples.

Me and Stephen are working on exception handling right now, so it will be much easier to debug.
