I moved where compiled/linked things from the module bin directories go. This addresses a frequent source of bugs and complications in the build scripts caused by SCons being sloppy about differentiating between the source and target directories when using a repository. Sorry. The new directories are still added to the path by imppy.sh should you can still call your module binaries by doing ./tools/imppy.sh mybinary arguments or .tools/imppy.sh myscript.py arguments

In a change that is less likely to be noticed, there is a new benchmark folder in modules where you can put benchmarks to remove some annoying fiddling in the sconscripts.
