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 .

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.

Assertions are now properly decided before running the main solver.
...
Updating does not work yet. The test case works fine for installing/removing
the correct packages however. Weak (update/feature) rules are entirely ignored
so far.
Watches are on literal ids rather than literals to save on function calls
and memory usage. So a few methods for literals now have an id counter part.
This should probably be refactored to have the literal versions call the
id ones instead.
