Chat flags to toggle onscreen debug info

[bploeckelman]

It will be very useful to be able to toggle some features of the debug text individually via in-game chat.

These flags should be globally available so that anything that draws debug text onscreen can query the state of each flag, and draw or not draw accordingly.... so I'd suggest that they either get declared as extern in Common.h (and then initialized in Common.cpp which doesn't exist yet) or that they get added to Strategizer. Personally I'd prefer to just have them global in Common.h.

Here are a few flags that we could start with:

[ Global ]

• /drawAll (turns all flags on)
• /drawNone (turns all flags off)

  [ Agent specific ]

• /drawAgentState (toggles drawing of Agent's current State)
• /drawAgentOwners (toggles drawing of Agent's current parentManager name)
• /drawAgentTargets (toggles drawing of lines to Agent's current unitTarget/positionTarget)

  [ Manager specific ]

• /drawManagerUnitCounts (toggles drawing of unit counts for all managers [currently top left of screen])

  [ BuildMgr specific ]

• /drawBuildQ (toggles drawing of the BuildManager's queue and stack)

  [ Other ]

• /drawAPM (toggles drawing of actions per minute)
• /drawMineralRate (toggles drawing of rate of mineral gathering [note: calculating this still needs to be implemented])
• /drawGasRate (toggles drawing of rate of gas gathering [note: calculating this still needs to be implemented])

Please add other suggestions in the comments, and feel free to tackle this issue if no one else is working on it!

This functionality is in place as of 4c50d5105187ec64e78e16d2241b3a65b29ece80

Supported flags: drawNone drawSystemDetails drawSquadDetails drawAgentDetails drawAgentTargets drawBuildQueue drawBuildStack drawReserveMap drawMapBounds

TODO: drawBuildQueue/Stack need to be able to be toggled separately, refactor BuildManager::drawDebugText() into two methods and update DebugFlags::draw() to reflect changes
