+++ This bug was initially created as a clone of Bug #1056253 +++

Description of problem:
As a result of enabling the security manager to resolve MVEL evaluation security issues, a substantial performance drop has been identified in FSW/BRMS/BPMS 6 builds. This performance drop is substantial enough that it could undermine the competitiveness of these products.

Hence disable the security manager by default in standalone.sh, and provide e.g. standalone-secure.sh with it enabled.
This also needs to be done for the domain mode.
