ENH: Split cmLocalUnixMakefileGenerator2 away from cmLocalUnixMakefileGenerator to be a stand-alone generator.

ENH: Initializing translation map using the PWD environment variable and getcwd functions to automatically translate logical paths involving the current working directory.  Also added the JoinPath method to aid users of the SplitPath method.

BUG: Fix for bug 1100.  If EXECUTABLE_OUTPUT_PATH or LIBRARY_OUTPUT_PATH is a relative path it should be converted to a full path relative to each build directory.

ENH: Moved reference from local driver targets (like build.local) into individual target rule files.  Main rule is now empty, except that clean.local may remove files registered for cleaning.

ENH: Implemented support for include/complain regular expressions for dependency scanning.  This now includes the possibility that scanning will return failure and the build will stop.

ENH: Added generation of CMakeDirectoryInformation.cmake file in each directory next to the Makefile.  The include file search path is now stored in this file instead of duplicating it for every object file. This will also allow more information to be passed in the future.
