Reworking job system. Regression in current version related to cleaning supplies.
Corrected cleaning supplies regression.
Fixed crash on city not having a cleaning cupboard and elf wanting more supplies.
Fixed bug character in influence meter
Made entity generation based on the imported city. Use E's and D's in your city to spawn people.
Renamed elf to citizen
Made hud elements react to screen size
Changed lots. See full message.

- SmartEntity renamed to LocEntity
- Added AIEntity which ate "virtual void update()"
- Entity::GLOB_ENTLIST removed, functionality moved to AIEntity::ai_list
- Garbage no longer shows up in AIEntity::ai_list
- Split the Component part of City into Mapview.
  - This is a move to a more MVC-like architecture
- "virtual void Entity::render(Graphics&) const" has been changed to "virtual char Entity::render() const"
  - I think this change is self-explanatory
- Added pretty wall rendering. This required the tiles to be resized to 6px x 12px.
  - I spent an hour looking for a preinstalled square, monospace font but no luck.
- Added "void Graphics::drawChar(int, int, char)"
- Added Controller. This takes KeySyms and manipulates the currently displayed view.
- Added unit listing. This is accessible by pressing 'u' and displays all AIEntities.
- Added an announcements tracker. Accessed by "void announce(const string&)" and displays the most recent 3 messages.
- Added a ComponentList that simply composes several other Components.
  - This makes it much easier for the Controller to swap out views
Moved MyController to ViewStack. Added command line alternative to stdin.
Added Security & Department, added job categories, added superiors.
Here is a small city for you.

Merge remote-tracking branch 'george/master' into georgemerge
