Consolidate the exec/eval bits, switch anonfunc to better_exec, etc

The methodpool, ${@} expansions, anonymous python functions, event handlers
now all run with the same global context, ensuring a consistent environment
for them.  Added a bb.utils.better_eval function which does an eval() with the
same globals as better_exec.
