Use bison instead of bison++

The += operator should also take the environment variables into account
Solved problem when & in redirect operator on command line
Solved syntax error when SPACE was follewed by SPACE
Removed kdevelop3 project files
Enable debug info in debug build on linux
Added support for foreach function
Fixed dependency problem for implicit rules with extra dependencies
Increased gnu make compatibility: allow implicit rules without commands
Solved wrong error message when it cannot build a target in mhmake_dbg
On windows: when checking the extension of a command: make sure a / does not cause a wrong decision
Added safety against recursive implicit rules.
Fixed wrong check on failure to open makefiles.
Make sure no message is printed when -include is used
flex and bison generated files: make sure the #line statements have the correct line numbers for the debugger after having added one line in the beginning of the file after running the flex/bison.
Make sure that the variable defined just before an error or message/info macro is defined when the message is generated.
mhmake_dbg: print error message when a target cannot be build because the directory of the target does not exist (and no rule is defined for it)
Reformatted message/info macro output
Also print makefile and line number when using error and message macro
Solved crash in mhmake_dbg when -C is specified on the command line
Solved problem in macro expansion when 2 patsubst inside each other
addprefix should not give an error when done on an empty string
Use comspec when echo is followed by a pipe character (piping is not supported by the echo internal command of mhmake)
Solved possible stack curruption (there was little chance that this was occuring)
