When changing watched literals of a rule, update the parent's next pointer
...
The previous rule was not previously updated to point to the next rule when
removing a middle rule from the watch tree for a literal. This resulted in
jumping from one literal's watch tree to another's, which could then jump
back to the original and cause infinite loop in a case like #265 .
Fixes #265

PHP 5.3.2 segmentation fault fix
...
For some reason, using the SqlFixedArray causes a Segmentation Fault during
an install or update. Changing to a simple array fixes this issue, but in
turn uses more memory. Which is why there is the version test.
