bootstrap script should be enhanced to also accept lmod/modulecmd.tcl

[boegel]

The bootstrap doesn't work yet with Lmod or modulecmd.tcl.

Shouldn't be too hard to fix the bootstrap script for this, just also check for lmod or modulecmd.tcl, and set $EASYBUILD_MODULES_TOOL accordingly.

work around (for bash and Lmod (replace Lmod with tcl etc etc)

mkdir -p /tmp/fake
echo 'echo Usage: module' > /tmp/fake/modulecmd
chmod +x /tmp/fake/modulecmd
export PATH=/tmp/fake:$PATH
export EASYBUILD_MODULES_TOOL=Lmod

[stdweird]

other EASYBUILD_MODULES_TOOL values can be EnvironmentModulesTcl and default EnvironmentModulesC

fixed by #869, so closing this
