Lots of little bug fixes and a couple of major ones.

• Pushing was horrendously broken in many different ways
  • You can no longer shove blocks through walls
  • You can no longer move blocks several spaces away
  • You can no longer push diagonal-adjacent blocks
• Added a current block display in the upper half of the map
• Darkened the floor and added a highlight onto the block target tiles
• You can only pull one step at a time now
• The timer is less stupid and won't allow games to carry on indefinitely (well maybe only if you're incredibly fast)
• Max time decreases properly now
• Pull bonus is reset properly now
• Slight adjustment to title graphic on score screen

There's still an occasional bug where blocks end up on top of each other. Like most things, I think this has something to do with pulling blocks.
