Made DSPTool more informative and actually fail when compile fails (right now it kept creating invalid files)
Also, created an example test which uses the INCLUDE directive. Tests are much shorter and human-readable now! git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@3064 8ced0084-cf51-0410-be5f-012b33b47a6e
