Committing todo.txt
Added some structures to SerialPacket, and serial.cpp

I've also created the Statistics structure for simplicity.
Hooked up the new serial code, nothing broke
Restructured the common/ directory, and simplified the build process
Removed common/ from the build process, and the DEBUG flag

The common/ directory is empty, only containing more directories to be
built, and the DEBUG flag isn't being used.
Implemented SharedParameters system in the client (read more)

Here are more tweaks:
* InWorld's quit event now exits to the main menu, bypassing a relayed disconnect message
* InWorld's disconnect hander no longer throws exceptions (dropped creation packet bugfix)
* CombatData's internals now point to std::pair objects
* Enemies are stored in a global list
Moved the server's data containers into common/gameplay
Removed the UID counters from the data containers
Began unifying the server and client side character classes

This commit won't build
Merge branch 'dev-charshare' (early part) into develop (read more)

Moved the server's containers into the common directories, and removed the
server's static members.

This commit does build, but the next commit in 'dev-charshare' won't so
I'm merging this while I can.
Merge branch 'dev-charshare' into develop (read more)

Using several branches never really works out well for me. I'm merging
these changes back into develop, because I want to undo the shared
parameters change, but that's tied up with something else. It's just
easier if I do this.
Removed the shared parameters structure (read more)

I've also stopped using a separate branch for sharing the CharacterData
structre. This commit won't build, mostly because I need to refactor
InWorld to handle the loss of the PlayerCharacter class.

I should probably rename SQL's tables too.
Added the GRAPHICS flag, to simplify the gameplay structures
Moved the scenes up one directory level, subdirs no longer needed
Threaded the tables through the scenes
Entire project is building cleanly again, but characters are static
Refactored some code from InWorld into methods in CharacterData
Solved a few items on the TODO list
Refactored UDPNetworkUtility, and tied it to SerialPacket
Bumped the network version
