== Constraints - Code Cleanups ==

* Tidied up coding style of code in editconstraint.c
- removed blank lines, made whitespace-use more consistent

* Shuffled code in editconstraint.c and BIF_editconstraint.h so that it was in a more orderly fashion

* Reduced code redundancy in test_constraints
- tests which can apply to general constraints (target existance, and clashes with the owner) are not copied out for each constraint that needs it
- ChildOf constraint now gets validated too (before it was missing such checks)

* Recoded the way PyConstraints build the menu for displaying scripts available for use. It now uses dynstr instead of guessing how much memory to allocate for each entry
