Cleaning the cages

The last few weeks were centered on cleaning up the memory leaks.

Valgrind is a great tool; unfortunately it does not work with libgcrypt. Once the libgcrypt code is mocked out though, I was able to find and clean a lot of memory leaks during tests.

On the features front, circus gained a single new feature: the recipes now support size ranges (instead of just fixed sizes). When a range is defined in a recipe, the generated password size will be randomly chosen within that range.

Now that the cages are clean, we can go on adding new features…
