remake 4.1 +dbg 1.1 released

1.0 added profiling and getting callgraph info using the --profile option.
1.1 fixes a bug in remake's "set" command which caused a SEGV and adds a "setqx" which expands the value given it before assigning to a variable. Both setq and setqx commands also now allow setting a variable that hasn't been defined before.
