ENH: major change, the cmMakefile now contains a master list of cmSourceFile objects, the source lists reference the list via pointers, also you can now set properties on a file, like compile flags, abstract, etc.

FIX: foreach function-blockers were using expanded args. Add virtual func to specify if function blocker needs them expanded or not.

Add ccommand for executing commands on the system, so by using ADD_CUSTOM_COMMAND, you can make rules to do some system commands during build. Currently supported commands are copy and remove. Others will follow.
