Added order consistent PropertiesManager class, and made the PN use it for the config file.

PropertiesManager works like java.util.Properties, except it extends LinkedHashMap<String, String>. This guarantees order, so it can reliably be determined which entry came first. The PN is supposed to work on this principal for conflicting entries that are equally specific, but because it was based on the Properties file, that couldn't be guaranteed. Now it can be, so this removes the warning (and the TODO).
Changed *_score to *_pscore, added set_team_options, added java and mscript API for multi-scoreboards

Fixes for crashes and stacktraces
Updated commit guidelines.
Removed unused imports.
I have added get_pwalkspeed, set_pflyspeed, get_pwalkspeed, and set_pwalkspeed. The code was created from my first version. Hopefully there is nothing that needs changing. :D

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.
Added vehicle_(enter|collide)/entity_explode/get_entity_(rider|vehicle), moved set_entity_rider out of sandbox
Fixed compile error. Upped redis dep version. Began MySQL integration.
Fixed bug 2660. Also updated DocGen and scoreboard code to prevent fatal errors when building docs.
Changed get_values from using startsWith to a more proper namespace regex.
