Red-Point SVNCode

***Reverted back from version 29 to 27 and then added the following changes, due to the SVN being corrupted from a merge. This I determined to be a sourceforge error as stated here : http://stackoverflow.com/questions/2324187/merge-trunk-into-branch-with-svn-secure-connection-truncated
Implemented the XML screen loader.
Revamped main a tiny bit.
Created a Screen Test screen which allows you to select via the console the different windows to navigate through.
removed LoadScreens.h ScreenFunctions.cpp/h no longer moduling screens load functionality this way.
Might in the future bring back ScreenFunctions.cpp/h for screen specific functionality like loading main game or changing a label value from 'Space Bar' to 'Ctrl' when a user wants to change key configurations.

renamed the load sprite and image files to have capital L in Load instead of lower case.

Debugged an error with loading all asset files... very close to loading images and creating screens.

Added more screen xml text to sample.xml.
Separated out the two tests (Screen and Physics test) into their own .cpp files.
Remove un-needed functions in ScreenFunctions.(cpp/h).
Cleaned main up.
removed UnitTests.cpp.
Added and removed member variables from Screen.(cpp/h)

forgot to add files

moved some asset folders around and added some new ones. Updated sample.xml. Added loadImages.h and loadSprites.h header files

Implemented unit tests in main.cpp. Added UnitTests.cpp, UnitTests.h.

updating project file

Made some changes to the xml layout which incorporates assets at the top instead of per element of a screen. Still need to finish out the xml sample, just committing now so I can work on my desktop to finish this part off.
