FIXED: wrong link to script
CHANGED: Script which installs phedex
The changes relate to the creation of the env-anse.sh
Now, the variables are kept when the script is created and are not replaced by values.
Ex. PHEDEX_ROOT is kept as '$TESTBED_ROOT/phedex' instead of '/data/TESTBED_ROOT/phedex'.
If the installation needs to be moved for any reason, one only needs to change TESTBED_ROOT
and not to replace folder name in all variables
