Merge pull request #113 from ProjectBarks/master

Added set/get fly and walk speed
Fixed failing documentation test.
Refined the unexpected error handler, and wrapped jedis exceptions.

Now, the unexpected error message handler will output the line of code properly if there are variables or strings in them. If there is a variable, it is printed out with the name, but the value that is currently assigned is printed out above it. This should make reproducing the errors much easier, as the code can almost be copy pasted now. Also, the JedisConnectionExceptions are wrapped into CRE.
Added array_unique, and unit tests.
I have fixed a enchantment method because there was no way it could throw and I alos added on ground to pinfo
